Proportional brake controller automatically levels when mounted within a 70-degree vertical range. Includes digital display, 3 boost levels, battery protection and continuous diagnostics. Easily transfer between different automobiles.
With a proportional brake controller, you can get heavy-duty emergency braking, general braking or slow-to-an-idle braking for your trailer automatically. The intensity with which your trailer brakes are activated and the rate at which they are applied are dependent on the deceleration of your tow vehicle. This means that, unlike time-delay controllers - which send the same amount of preset power to your trailer brakes every time - proportional controllers are able to adapt to every braking situation differently. So, if you slam on the brakes in your truck, your trailer brakes will activate with that same extreme intensity. And if you merely slow down as you approach a red light, your trailer will gradually brake in the same manner. Just set the initial power level, select a boost setting, and you're good to go.
As long as the Primus IQ controller is properly mounted and is pointed in the direction of travel, it will sense - via an internal inertia sensor - how your tow vehicle brakes. This inertia-based sensor responds to the deceleration of your tow vehicle as you brake by signaling the controller to send out enough power to your trailer brakes so that they are activated with an intensity that matches. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.
Aside from smoother, more efficient braking, Tekonsha's Primus IQ brake controller also offers a boost feature that gives you more initial braking power for those times when you're towing heavy loads. You can switch boost levels so that the power output to your trailer brakes automatically starts out at either 13 percent or 25 percent of the predetermined power setting.
So, if you boost the initial power so that your trailer brakes activate with 25 percent of the overall intensity at the start, the brakes will reach maximum braking faster. This is particularly beneficial if you are towing a heavy load because the intensity required to stop that load may be far greater than that needed to halt your Audi A6. Therefore, sending out more initial power to the trailer brakes - and causing them to reach maximum braking faster - allows you to better control the trailer so that it doesn't push your tow vehicle before coming to a complete stop.
If your trailer weighs less than your tow vehicle, no boost is needed. But if you wish to set the boost so that your trailer leads the braking of your towing setup, you can select level B1. The following table gives an indication of when you might use the different boost levels and the power increases that they offer.
|Approximate Gross Trailer Weight||Boost Level||Increase in Initial Power Output|
|Less than tow vehicle GVW||B1||13%|
|Equal to tow vehicle GVW||B1 or B2||13% or 25%|
|Up to 25% more than tow vehicle GVW||B2 or B3*||25%|
|Up to 40% more than tow vehicle GVW||B3*||25%|
*Both B2 and B3 offer a 25-percent boost in initial power. But the braking curve for B3 is more aggressive than that of B2. This means that, even though you will start out with the same intensity when using these boost levels, you will get an overall more aggressive braking experience with the higher level. So if you use B3, you will reach maximum braking sooner than if you use B2.
The Primus IQ offers advanced safety features to prevent damage to various components of your towing setup. For example, when it is not in use, this brake controller will be in power-saving mode. In this setting, the power draw falls to minimize drain on your Audi A6's battery.
When you stop at red lights, or any time that your truck and trailer are at a standstill with the brakes applied for more than 5 seconds, the Primus IQ's "hold" feature will activate. When this happens, the power output to your trailer's brakes will be reduced to just 25 percent of the preset power setting so that the brakes will not overheat.
If ever there is a time that you need to brake your trailer separately from your tow vehicle - when traveling down a steep incline, for example - the manual override is easily accessible. Pushing this slide bar engages the brakes on your trailer with full power. In addition, when you activate this override, the brake lights on your trailer will illuminate, properly warning those behind you of the braking action of your rig.
In addition to all of those safety features listed above, the Primus IQ offers diagnostics such as:
The self-leveling feature of the Primus IQ ensures that the brake controller continues to function even as you drive up steep hills or through the mountains. Simply mount it in your cab at a vertical angle that is between 0 degrees (level) and 70 degrees, and the controller will level itself automatically.
Note: The Primus IQ must be mounted on a level horizontal (side-to-side) plane and must be lined up with the direction of travel for the internal sensor to function properly.
Installation is a snap. After mounting the Primus IQ unit in your cab using the included bracket, hardwire one end of the included pigtail harness directly into your Audi A6. The other end plugs into the brake controller. To transfer the Primus IQ to another vehicle or to remove it for storage, just unplug the unit and snap it out of the bracket.
For even easier installation, a vehicle-specific wiring adapter (sold separately) is available for most newer trucks and SUVs. One end of the custom adapter plugs into your Audi A6, and the other end plugs into the controller - no hardwiring required.
Note: If a custom brake-control wiring adapter is not available for your Audi A6, one of the following will be required:
20-Amp circuit breaker (9506P - sold separately) for 2- to 4-brake applications
30-Amp circuit breaker (38630 - sold separately) for 6- to 8-brake applications

Today on our 2003 Pontiac Vibe we'll be installing the Tekonsha Primus IQ brake controller, part number TK90160, using the e-trailer brake controller install kit, part number, ETBC7. To begin our install we'll first go ahead and mount our 7 pole bracket to the 7 pole connector and then installing a Tow Ready no drill mounting bracket, part number 18136 onto the 7 pole connector bracket. For this application we'll be mounting the bracket upside down to allow for the 7 pole bracket to sit up tight and not drop below the hitch receiver tube. Note we'll go ahead and take our 7 pole connector and wrap it up with some black electrical tape. We're going to go ahead and trim the purple wire short as it's for trailer reverse lights which aren't going to be needed in this application. Now with our 7 pole connector mounted to the vehicle we're going to go ahead and remove the 4 pole connector exposing the green, yellow, and brown wires. We'll then go ahead and strip back the wires and prepare to install butt connectors.
We'll take the 4 pole harness that's already installed on the vehicle, take the wires, strip them back, and add butt connectors. We'll then take the butt connectors and add it to the 7 pole wires we just exposed matching color for color, green-to-green, yellow-to-yellow, and brown-to-brown. We can go ahead and cut the white wires short as it will not be needed for this application. We'll use the white wire that comes from the 7 pole connector. Next, we'll take the gray duplex cable supplied with our install kit, route it over the receiver tube, strip back the gray sheathing and then strip back the black and white wires. Take the wires, strip them back. We'll take the black wire and secure it to the black wire with the pre-installed butt connector coming out of the back of our 7 pole.
This will be the 12 volt power supply to our 7 pole connector. We'll take the white wire from our gray duplex cable and attach it to the blue wire with the pre-installed butt connector. This will be the power supply for our trailer braking. Now with all the connections made we'll go ahead and wrap it up with some black electrical tape. This will help keep our connection points clean from dirt, dust, debris, and moisture. We'll go ahead and start routing our wire to the frame and ultimately the gray duplex cable will get routed up through the engine compartment into the top of the engine bay.
Keep in mind when routing your wires to stay away from any moving components such as the steering or suspension or excessive heat such as the exhaust. We'll use some black zip ties to secure our wiring as necessary. After we route the gray duplex cable and the white wire with the pre-installed ring terminal up over the exhaust hanger. We can then go ahead and take the self-tapping screws supplied with the install kit and secure it to the white wire with the ring terminal to the frame providing the ground for our new 7 pole and 4 pole connector. Now we'll go ahead and complete routing and securing the gray duplex cable as we route it to the bottom of the engine bay. Once we've completed securing the wiring we can go ahead and cut off the excess from the zip ties to clean up our install look. Once we make it to the bottom of the engine bay we'll then go ahead and take a pull wire to assist in routing it up through the engine compartment.
Pull wire could be a stiff piece of wire. In this case we're going to use a piece of air tubing. We'll feed it down through the engine compartment where we can then go ahead and attach the gray duplex cable to it using some black electrical tape. We'll now go ahead and use the pull wire to pull it up through the engine bay. Once we get to the top of the engine compartment we'll route our gray duplex cable along the fire wall and ultimately over to the battery making sure we have plenty of length. We'll then go ahead and cut off the access length and strip back the gray duplex because the white wire will get routed into the cabin of the vehicle. For this application there's no manufacturers grommet to use to route through so we'll need to install our own grommet. We're going to be using the Spectro Snap bushing, part number SWC8057. We'll go ahead and start with a pilot hole and then use a step it process enlarging to a 7/16ths where we can install the snap bushing. Once we have the hole drilled out we'll go ahead and put the snap bushing in and then route our white wire into the cabin of the vehicle. Next we'll take the cut off of our gray duplex cable from our run from our 7 pole and route it in through the snap bushing. This will provide power and ground for our brake controller. Now with all the wires necessary run inside the cabin of the vehicle we'll go ahead and move inside where we'll need to start installing and mounting the brake controller. For this application we'll be mounting the brake controller on the top of the dashboard. We'll need to go ahead and drill a hole through the dashboard and install the Spectro snap bushing, part number SWC8055. Now with the hole drilled out we'll go ahead and install the snap bushing. We'll then take the brake controller pigtail and feed it down through the snap bushing underneath the dash. Once we have it pulled down underneath the dash we'll then take the red wire and route it over to the vehicles brake switch. To test your wire you can use the test light taking the clamp and grounding on side and then using the test light to find the wire that's hot only when the brake pedal is depressed. Note, some applications it maybe necessary to have the key in the auxiliary mode powering the brake switch. For this application it's going to be a green wire with a white tracer. Now that we've identified the wire we'll go ahead and use our quick splice connector feed it over the manufacturers wire and then take our red wire and slide it into the quick splice connector. We'll crimp it down and close the clasp. Now we have this connection made we'll start making the other three connections. We'll go ahead and take the three remaining wires from our brake controller pigtail and strip them back and then go ahead and add the butt connectors provided with our install kit. We'll take the white wire that we ran into the cabin of the vehicle, cut off any excess, strip it back and attach it to the blue wire for our brake controller pigtail. This again is the power provided to our 7 pole connector for our trailer brake. Next we'll take the gray duplex cable, strip it back and then strip back the wire. Match it color for color, black-to-black, white-to-white for our brake controller pigtail providing power and ground for our brake controller. Once we've made our connections we'll go ahead and wrap it up with some black electrical tape. Then we'll secure them as necessary underneath the dash,. Cut off the excess from the zip ties and clean up our install look. Well take the pocket from our brake controller and install the pocket onto the dash. We'll use the hardware provided with our install kit to secure it. We can go ahead and take the pigtail wiring and plug it into the back of the brake controller. We'll install the brake controller into the pocket. Now we'll move into the engine compartment. We need to install two breakers. One for the brake controller and one for our 7 pole connector, 12 volt power supply. We'll go ahead and install the 40 amp breaker first suing the self-tapping screws provided with the install kit. Our second breaker will be determined by the size of the trailer or load supplied by the 7 pole connector. This can either be a 20 or 30 amp breaker. With both breakers installed we'll start making our connections. We'll take the black wire from the 7 pole connector, cut off any excess length, strip it back and add a small ring terminal. We'll take that ring terminal and then install it on the silver side of the 40 amp breaker securing it with a star washer and nut. Next we'll take the gray duplex cable that we ran into the cabin of the vehicle for power and ground for the brake controller and then we'll split the gray duplex cable sheathing. Once we remove it we can take the black wire route it to our second breaker. We'll cut off any excess length, strip it back and add a small ring terminal. We'll secure the ring terminal of the breaker, take the white wire and route it over to the negative battery post. Here we'll cut off any access, strip it back and add a large ring terminal. We'll then go ahead and loosen the negative battery post terminal and install the ring terminal onto that post. For this application the stud is not intended to be completely removed from the terminal. We'll just back it off, cut a small slice into the ring terminal, slide it over the post, and then re-secure the nut, securing our wire to the negative battery post. Next we'll take the remaining black wire from our gray duplex cable to make two leads going from the copper side of our breakers to the positive battery post. First we're going to strip back both wires and add small ring terminals. We'll then take the ring terminals and attach them to the copper side of our breakers securing them with a star washer and nut. We can now go ahead and tighten down all four post on the breakers. Now we'll route the power wires following the white wire we routed to the battery already and then to the positive battery terminal. Cut off any excess from the power wire, stripping back, and add two large ring terminals. Then remove the nut from the positive battery post stud, install the ring terminals and then re-secure the nut. Now we'll go ahead and secure any wiring underneath the hood as necessary and cut off any excess from the zip ties to clean up our install look. Now with all our wires installed and secured we're ready to go ahead and test our new brake controller and 7 pole connector. Once we install the trailer wiring our brake controller will show C for connection. Then when we press on the brake pedal the numbers will increase showing the output to the trailer braking. We can also use the manual hand sweep on the brake controller to supply power to our trailer braking. Now that we know our new 7 pole connector works we're ready to hit the road. That does it for the install of our Primus IQ brake controller, part number Tk90160, in conjunction with the e-trailer brake controller install kit, part number ETBC7, for our 2003 Pontiac Vibe. .

Shipping was great. Stared at it for a couple of days before unpacking. The trailer connector mounting was easy with the holes almost matching the existing holes on my 2013 Toyota Highlander. The first four wires are a snap, they are just plugged into the existing four pin connector. I routed the two wire cable towards the front using ty wraps and improvised L brackets fixed to existing chassis screws. I mounted the Circuit Breakers on the inside of the left fender making sure there was hood clearance (see photo). Then I hit a snag. There was no easy way to get the brake and 12V power wire to the brake controller inside the car. For grins, I goggled "brake controller video" for my car and came up with a video made by "eTrailer." (Thank you eTrailer) Three things from the video helped me: wire access from inside the car through the firewall, a place to mount the controller and how to locate the brake wire. After the installation I had 18" of two wire cable left over. The install took me about six hours. (I'm 71 and I took my time.) A couple days later I connected the trailer for a test ride. The brake controller worked like a dream. Things I liked: Retaining the four wire trailer plug setup next to the seven wire trailer plug. Controller display works but you don't have to look at it. The two wire cable was adequate for the job. Being an Engineer (retired) I worry about things like that. Thing I didn't like: The mounting plate for the trailer plug is a little weak. A stiffer plate would have been better suited for me. and, oh yeh, somebody else to install it. ;=) 135250
Installed quickly an easily into my 2009 GMC Sierra 2500HD by wiring up to the factory harness. Be sure to watch the etrailer.com video to see which wires need connected at the fuse box in the engine compartment! (Easy hook-ups, just need to make sure you see which ones get hooked up and where.) And if you don't use your ash tray, these brake controllers squeeze nicely into the ash tray compartment/recess in the lower part of the dash. Makes a great place to keep most of the controller out of the way and it's easy to install (you will have to create 2x new holes in the plastic detachable controller mounting bracket but its very easy - you can see the mounting screws in the 'new' holes and the old holes go unused as shown in the photo). Only had a trailer hooked up once, but the controller functioned as designed. I think the 'Boost' function will come in handy if I use a well-loaded trailer and need some additional stopping power from the trailer. 135875

I installed this on my 1997 Chevy K1500 pickup to pull my farm trailer, Kubota tractor, and it's implements (total of about 5500#s). I bought my truck new in 1997 with the towing package. eTrailer had a number of links related to the installation, but the most helpful was the one that identified the blue brake and orange power wires that, in my case, were preinstalled at the factory. That made the job significantly easier. What I thought would be the most challenging part of the install turned out to be simple, but only because of pure, dumb luck. Because I had installed aftermarket security and stereo systems shortly after I bought the truck, there was no way to identify/compare the pictures/discussions to identify the hot brake wire under the dash near the brake (other than that it was likely a white or gray wire). The circuit tester (purchased with my order from eTrailer) turned out to be a godsend. Unbelievably, the first white wire I tested turned out to be the hot brake wire! I was very lucky to hit the correct wire on the first try. The first time I hooked up to my trailer, the system worked flawlessly... exactly as the instructions described. And the performance is excellent. Note: I double/triple checked connections as I worked. I highly recommend doing this. Hunting down electrical connection malfunctions is not something you want to do. Overall, I'm VERY happy with my purchase and the support from eTrailer. I highly recommend this product and eTrailer. 98210
THANKS for the Brake Controller unit from ETrailer. It arrived w/in 5 days from your MO location to my So CAL residence. Even as an Engineer/Scientist from the Delta IV rocket program and no experience with brake controllers, I was able to install this unit by myself. Your continued (live human) support and online video clips proved to be the key elements to this installation...without my symbolic pocket protector. I have attached a few images of the unit, mounted to the fuse-panel cover (3/16 attachments with locking hex nuts) in a 2006 Toyota 4Runner SR5 (with factory tow package). The placement of the unit onto the panel cover allows a new panel cover (no holes drilled) to be used when it is time to sell the vehicle. 85308
Pictures of the install. Approximately a 20 min job. First picture my finger is pointing to the factory plug with the etrailer supplied harness plugged in. Note the harness did not specify that the white common with the ring terminal should be connected to ground. But then again that SHOULD be obvious. I will be towing this weekend so I will rate the product then. One minor gripe is that there is always power to the unit which is a battery drain (as evidenced with the key out of the ignition and the unit stayed on) Not sure as to the impact but the controller can always be unplugged or removed. Sorry for the dirty floor mats in the photos. 115201
The Tekonsha Primus IQ controller is a well made compact unit that is perfect for my FJ. The ETBT7 wiring kit has all you need to go from 4 to 7 pin connectors. I was worried about how to remount the 4 pin, but the new 7 pin has a 4 built in it. It is a very clean install. The kit had everything needed to install, including a test light. The Tekonshcontroller and the wiring kit are high quality and have complete easy instructions, and had everything needed for the install. Etrailer didn't have the ETBT7 in stock when I ordered and I paid for expedited shipping. They followed up with emails and calls to inform me what was happening, and offered to refund the shipping fee. I told them just expedite it when it came in and they did, got to me in two days. I recommend trailer highly, they kept me informed, were prompt, friendly, and concerned, and paid attention to detail. If only other companies followed their example... Excellent prices, Great product line, great company, great staff. I will use them for all my trailer needs. I Recommend them highly. 130304

I purchased the Tekonsha Primus IQ Trailer Brake Controller and the wiring kit for my Toyota 4Runner. It was simple installation and the customer service was EXCELLENT! They sent me extra schematics I needed by email and was very supportive! I will definately do business with them in the future. 78575

I chose this device based on my trailer repairman's brand recommendation. He usually has them in stock but was out. I got mine before his order came in. He also did not have a wiring harness for my vehicle so I ordered that, too. This is the first time I've ordered anything significant that I knew virtually nothing about. From the descriptions and pictures on the etrailer site it was easy to look up what I needed. I also read on the site about time control vs proportional and then knew the proportional would be good for me. I have a new camping trailer that has electric brakes; need the controller to operate the trailer brakes. The product quality of the brake controller appears very good. The wiring kit is quite substantial. My mechanic will wire up for me this week end and I'll have his opinion then. I am very satisfied with the speed of the delivery and the quality of the products. thank you 84360
by: Sam S.10/09/2013
Like other reviewers the biggest challenge was getting the cover plate removed (and replaced) to access the factory connection. The connection was at the very top of the wiring bundle and I was able to cut about 1/2" of the tape holding the bundle together very near the connection to gain access without removing or cutting all of the tape. The ground terminal was easily accessed and the installation was quick and mostly painless. The instructions to set the braking level was spot on. I have a Sequoia with a knee airbag and tire pressure monitoring. I place the controller with the open back of the bracket allowing access to reset the tire pressure monitoring switch. 103222

Purchased the Tekonsa Primus IQ controller with wiring adapter for my Dodge Ram. Shipment arrived quickly and was exactly what I needed. Installation was a piece of cake. Cut an opening in the plastic stock dash location. Plugged the adapter into the Dodge plug under the dash and into the Primus. Worked perfectly. No fuss. Installed in about 10 minutes which included the time to cut the opening.. Picture will be poster... I was so happy with the service from etrailers that I ordered the Blue Ox Swaypro hitch. Thanks ETrailer.com! 112238
by: Ray B of Colo.11/18/2013
I purchased a Primus IQ from our local NAPA dealer and had already installed it in one of our Dodge trucks before I learned about Etrailer. Needless to say it cost a bit more than the one I ordered from Etrailer a couple weeks later. you cant return electrical products once installed. I received the one from Etrailer in a very timely manner. I was hoping it wasn't a #2 for it being so much cheaper, but it is just fine and installation was no problem because I already had Tenkonsha Voygers so just chop the wire and install new control unit. We have two trucks and pull various trailers, so am real happy with product and will further order trailer items from ETRAILER.COM. Thank you, just Ray 107693

I bought this product after reading several reviews. I recently purchased a Fun Finder 189FBS Travel trailer, and I needed a Brake Controller that was proportionally controlled. After my first trip with my 2012 Rubicon/ Fun Finder; I am very pleased with my purchase. This controller works best for my setup, on the "b1" boost level. Setup and installation took less than 2 hours, and I did it myself. The instructions and reference video from etrailer.com were very helpful. I was quoted nearly $400 to install this controller from my local RV shop. I bought it hear, spent 2 hours, and saved $250. If you can crimp a wire, and run a drill- You can do this! 80929
by: Brent B04/07/2014
This product plugged right in and worked perfectly as it should. I like the different boost levels as a quick adjustment between loaded and unloaded trailers. No messing with the gain controller to keep the tires from sliding. The special dodge plug made install a breeze and less than 5 minutes. Much better than splicing into wires. Plus eliminates the need to hunt for the correct wires. This controller works off of inertia so as it senses your truck braking it applies equal braking to the trailer eliminating the jerk experienced from other controllers. Shipping from etrailer was quick as well. Great overall product at a reasonable price. 124031
by: Kevin G.09/11/2012
Product works great, as advertised. The Tech at the RV dealer commented on the reliability of this brake controller, and the install literally took 15 minutes, start to finish. The supplied factory wiring harness made quick, simple work of the installation. The video on the etrailer website is right on the money as well. I have dealt with etrailer for all my towing needs since 1995, and they have never let me down. Great, quality products......quick delivery, and customer service that is second to none. There is no reason to shop anywhere else. Thanks etrailer.......you are the best! 54172
I ordered mine with the wiring harness for toyo and Lexus. Everything plugged in nicely and fit perfectly in a Toyota Sequoia under the steering column on the right side. The only suggestions is the that the factory wiring harness in the sequoia has absolutely no slack, so it you order this with an adapter for this make and model, it is a little to short to run it to where I have it. I really had to work to get it mounted. If it had a longer run by about 6 inches it would have been a piece of cake. I still gave it an excellent rating because other than that it was a 5 minute install. 116521

While I have not had the chance to use it yet pulling my trailer I picked this particular unit because of the reviews it has received from people that have and are using it. I had it professionally installed and it is working as the instructions say it should. The company that installed it had nothing but good things to say about it as well. I especially want to thank Nicole for her help and customer service she provided to me and I can promise you that all my future trailer needs will be purchased from your company via Nicole. Big Thanks to all of you. 56414
Great controler for the price. Easily mounted and set up using the vehicle specific harness. Installed in a 2003 Toyota Sequoia just under the key in the flat of the center cover. Perfect for the 0 - 70 deg mounting location required by this controler. Setup and operation just as was stated in user manuals. eTrailer was great as well, everything came together and on time. 84801
I am unable to correctly rate this product at this time because there is no Dodge 2013 harness with which I can attach it. If/when the harness becomes available (a year plus after the truck came out, of course), I will re-review the product. Note that lack of this harness is NOT the fault of eTrailer, but if you're purchasing this for a 2013 Dodge truck, you might want to wait. 73972

Plug and play is a true definition. My family was bugging me to go boating this last weekend and being the procrastinator that I am I had not yet installed a brake contoller on my 2011 Ram yet. Got the controller and Harness in the mail on Saturday after only 3 days since order was placed. The install took 10 minutes max including the bracket install and away we went to the River. Thanks etrailer!!!!! Would have never heard the end of it from my 14 year old daughter if we would not have made it boating!!!!! 46597

I have had a few different trucks in the past, all with brake controllers, some factory some not. So when picking one for my truck, I wanted something with as few a knobs, dials, etc as possible. I looked around on the internet and found the Primus, it was the middle of the road as far as sophistication and basic. It was shipped promptly and arrived within a few days. The installation was easy with great instructions. Would recommend to anyone who wants ease of operation without spending a fortune to get it. 91572

The tekonsha controller was easy to install with the help of the instructions, (very well written), and the video, specific to my 2006 Dodge Ram. Set up was also quick as I dialed the power setting to 7, and have just the right amount of braking for my empty trailer. When I loaded trailer for the first time, I adjusted the boost level to the b1 position and that was all that I need to do to have the safety of well adjusted trailer brakes at finger tip control. Very pleased with this pur hase. 109795
by: Al R.07/17/2014
I was very pleased with the installation. I had a dealer tell me it would take about three hours, which I knew was a stretch, to install a brake controller on my 2009 Dodge Ram. Including opening the package and looking at the installation procedures, it took me fifteen minutes to install. I had looked at the on line information that was provided befor purchasing the brake controller. It was a great experience. I have not had a chance to see how it works, but I am sure it will be fine. 141743
by: William B.07/24/2013
This item was in stock and shipped the same day. It arrived undamaged and the installation took about 15 minutes thanks to the wiring adapter that let me directly connect this unit to my 2007 Mercury Mountaineer. Hard to image that it could be easier than this. 91296

This is my third Tekonsha brake controller and the quality is excellent. I've got to say that your installation video saved me a lot of grief. I spent about 20 minutes trying to find the factory connector under the dash without success. The video showed me exactly where it was hidden. Without your help, I'd still be looking!! Your salespeople were helpful, too. Anything else I need for my trailer I'll be using you- and recommending you too. 108744

I cannot rate the Primus IQ controller yet as I have just received it.However, the instructions/disk are very clear and straight forward. What I can comment on is eTrailer.com. I don't think I have ever seen an online retailer with better customer service and online support (videos showing step by step installation instructions for almost every specific model truck) It took a real effort on eTrailer's part to provide this. Great job! 35943

The product was exactly as advertised, arrived very promptly, and I installed it myself in just minutes with the prewired harness for my 2007 Dodge 2500. I have not had the chance to hook up the trailer to set up and gauge the actual performance of the Primus IQ controller, but I don't expect any difficulties. I will definitely use etrailer again. For an actual performance review, you will have to wait a bit. Many thanks... 112245

Have not had a chance to road test yet but with the help of the videos and tech support, I had it installed in less than 30 minutes. Most of that was deciding where to mount it. Plugged in trailer and all information appeared in the window as described. Will have to review road test at a later date. etrailer expedited delivery which was very much appreciated and shows they aim to please in any way they can ....thxs guys!! 120080

Works very well in my 2012 Tundra. Worked first time. 55282

Recieved the product and it was very well packaged. Very easy installation with the wiring harness that I purchased with the controller. I highly recommend that. Followed the simple instructions inside and took it to the road. Went to Martinsville with our camper for race weekend and the brake controller worked awesome. I like the boost capability. It makes a difference if you have a lighter tow vehicle for sure. 123137

Great product so far. I'm a novice at towing and I got this controller in the mail 2 days before I bought my first camper ever. I found a video on YouTube that gave me step by step instructions on installing. I did it myself and hooked up to my camper for the first time. Worked perfectly. Also shipping was faster that I expected. Etrailer had the best price out of everyone for it. Glad I bought this one. 93130
I purchased the Primus brake controller after recently buying a 20 ft car hauler. The controller was a must due to the weight of the trailer and its cargo. The controller works great and the adjustment roller and turbo boost are fantastic and easily accessed. The installation only takes about 30 minutes too. Thanks Primus for a great product and thanks e-trailer for getting the product out to me so quickly. 63657

The Tekonsha Primus IQ Trailer brake Controller is exactly as listed, but the best part is all the great customer service from etrailer.com Orders are processed quickly and their videos are very helpful for installation! Allow a little extra shipping time for regular shipping and you will be good to go. ETRAILER is a great company to do business with and no they didn't pay me to write this! 130224

Shipping was fast, and the controller was offered at a great price. Saved some money and avoided issues by installing it myself. If there is something else I need, I'll check etrailer first, 84900
Installation was very easy, went into a 2014 Suburban with the tow package. Just 4 wires to splice in the cabin and attach the bracket to the dash. Then 2 wires under the hood for factory connections to power the unit. Took maybe a half hour ,start to finish. Have not had a chance to tow the trailer yet, buried in a snow bank, but expect it to work well. 112779
I wire this up on my 2004 chevy colorado, mostly to pull my 5x10 7000 GVWR dump trailer. Got the wiring kit from etrailer as well and it was pretty simple to install with the diagram and directions they sent. Just make sure to ground your circuit breakers well. I'm very happy with the whole set up. I can hardly feel the trailer behind me when i break. 70015

Good installation instructions for my 2014 Acura MDX equipped with trailer package. It already had a wired pigtail with an snap in attachment under the dash, so soldering and insulating the 4 wires was a snap. Delivery was within 6 days and the install took about 45 min. Haven't hooked either of the trailers yet but will give followup when used. 103810

Install was very easy in my 2008 Chevy Silverado. Haven't purchased the trailer yet so I can't rate its operation, but I'm sure it will work just fine. A bit of advice for others installing this or any brake controller in a 2008 Silverado...the truck's light blue/white stripe wire had faded with age to a pale green. Don't let that confuse you. 26493

This product was extremely easy to install - with multiple options. The only thing missing was the electrical connectors, but I'm not sure if they were supposed to be a part of the package or not. I really like the fact that I can snap the controller in or out of the vehicle. The product also performed great the first time out. 56775
What can I say? After watching etrailer.com video on installation of the unit, I installed myself with corresponding harness in less than an hour. Worked as suggested and got a better controller for less money than my local camper place was going to charge me to install their unit. Made me a believer on etrailer.com for sure! 89547
I just installed the Tekonsha Primus IQ controller and used the plug adapter 3035P to hook into my wiring harness on my 2013 Itasca Sunstar 26 HE. The chassis is a Ford F53 with a V10 motor, in case some one needs any reference to hooking into their motorhome wiring. Its was installed quicker than making my coffee! 124540
Ordering this product was easy and delivery was fast. etrailer.com was very helpful in choosing the right brake controller for my car. I installed the brake controller myself taking about 5 minutes. I purchased the brake controller to use for pulling my 27 ft tag along camper. It works great. 138217

Purchased electric brake controller for our 2000 Toyota Tundra as we are pulling a large camper. Very easy to install and adjust for camper weight using boost feature. Very happy with Primus and with etrailer as they got the controller to us a day ahead of delivery date. 50918

I purchased the brake controller for my 2008 Dodge RAM 1500, to pull my 28 foot travel trailer. Product installed easily and is straightforward. Customer service at etrailer.com was also EXCELLENT. I could not have asked for a better, more personal process. 55813

I appreciate the help and patience your technical personnel gave to me on installing the Primus brake controller in my GMC Sierra. I called twice (my fault) and both were very friendly and helpful. I will definitely shop from your company in the future. 63878

Second purchase for 2 nd vehicle and arrived on time both times well packaged and exactly as discribed. Called in on the second order and was very satisfied as to the knowledge and assistance given. I would not look anywhere else. Thank you etrailer.. 130882
As advertised!! works great.. Took about 15 min to install on my 2007 Sliverado. The 3015-p wire adapter saved me from cutting and splicing wires, well worth the $15.00. Tech supprot was great for a question I had. I will buy from e-trailer again! 137073
by: Mike B.03/11/2014
Product looks great easy install I took a little longer than 15 min because of my placement about 20 min. Shipping was right on time. I haven't used product yet we are going to pick up trailer 3/12/14 I will leave follow up review. Thanks etrailer 120197
