Proportional brake controller automatically levels when mounted within a 90-degree vertical range. Includes digital display, 3 boost levels, battery protection and continuous diagnostics. Easily transfer between different automobiles.


Features:

  • Brake controller activates trailer brakes in proportion to your vehicle's braking action
    • Automatically adjusts trailer's braking based on deceleration of tow vehicle
    • Activates immediately - no pausing like with time-delayed brake controllers

  • Plug-in, vehicle-specific brake-control adapter (sold separately) can be used for certain applications to reduce installation time


Specs:

  • Application: trailers with up to 3 axles (6 brake assemblies)
    • Designed for use with electric brakes only
  • Dimensions: 4-3/8" wide x 5" long x 2-1/2" tall
  • Mounting: between 0 degrees (level) and 90 degrees in the vertical plane
  • Limited lifetime warranty


Proportional Braking

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.


Power Boost for Heavy-Duty Towing

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 vehicle. 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 WeightBoost LevelIncrease in Initial Power Output
Less than tow vehicle GVWB113%
Equal to tow vehicle GVWB1 or B213% or 25%
Up to 25% more than tow vehicle GVWB2 or B3*25%
Up to 40% more than tow vehicle GVWB3*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.


Safety Features

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 vehicle'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:

  • Open ground
  • Overload
  • Output short
  • Faulty mounting
  • Power loss
  • No trailer connection

Automatic Leveling and Simple Installation

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 90 degrees, and the controller will level itself automatically.


Correct Primus mounting90-Degree Primus mounting

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 vehicle. 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.


Installation Accessories

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 vehicle, and the other end plugs into the controller - no hardwiring required.


Note: If a custom brake-control wiring adapter is not available for your vehicle, 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

Replaced an older brake controller with the TK90160. Installation was very straight forward and took less than a half hour. Hooked up the trailer, went to an empty parking lot, tested everything and adjusted the Boost feature. This unit is a superior brake controller. I do a lot of freeway driving as well as mountain roads (ie steep stuff) and I love the feeling of the trailer and the truck’s brakes working together. 563689

The brake controller and corresponding cable were exactly as advertised. Everything was delivered promptly and all items arrived in excellent condition. The videos of the installation provided on the website were very good and made the decision of the purchased easy. I am using this to help with electric brakes on a 38 foot travel trailer. The ease of installation was fantastic.The site has a wide variety of products and I am extremely pleased with my purchase. I will continue to do business with your company in the future and I will recommend it to anyone who has a trailer or travel trailer. Awesome experience all around 543923

install would have taken minutes on our Flex if Ford had left a few inches more wire on the connector. After getting supplied connector (Ford sent both halves of connecter in case of hard wiring) off, install was easy and everything worked as I hoped. 556799

This was bought with a 7/4 plug and a Tekonsha adapter cable for a 2012 Expedition for use with a 26 foot travel trailer. Very happy with this purchase. It was a pretty easy installation, but I did solder & used heat-shrink tubing for the wires in the back if the truck for a permanent connection. Up front was extremely easy. Ford was nice enough to wire all the Expeditions the same, regardless of whether it had a "tow package". The size of this unit is about average, but the bracket is not a large one, so the controller sits closely to the mounting surface. It mounts horizontally or vertically, so I mounted it almost straight up and down, which is good for me. My wife is short, leaving only a few inches from the dash to get knees, and there is no interference or banging into it, even though it's right out into open on the lower right of the driver's side dash panel. There were not a lot of location choices, so that's really it for ease of reach for manual use and adjustment if necessary. It is adaptive, so it does not try to engage too harshly, which makes it super easy to adjust to your truck and your braking style. Brake hard, it engages hard; brake gently and it engages only a little. Press softly, then harder, it reacts likewise. For anyone who'd like a nice controller at a nice price point, this is definitely a great choice. 527500

I have not hauled with this brake controller yet, but given the ease of installation and simplicity of controls i'm not sure how i could be disappointed. For my hauling needs (Only a 6k gvwr 2 axle trailer) this is perfect and a reasonable price for a proportional controller. Better yet was etrailer.com not setting false expectations on arrival. There are "two-day guaranteed" shippers that often fail to meet, while etrailer estimated a realistic travel time and actually beat it by a lot! 554652

Can you tell us exactly what the issue was? According to the Tech Services folks at Tekonsha, theres nothing unique to your model year Escape that would prevent the successful installation of this brake controller.

I have installed the Tekonsha Primus IQ Brake Controller with the ETBC7 Brake Controller wiring kit on my 1990 Chevy Blazer Scottsdale. Everything that I needed was included and the installation instructions were simple. We will be trying it out for the first time in early November when we are going to rent a small travel trailer. If we like the experience we may buy a travel trailer to go with our brake controller! Before and after pictures attached. Thanks for the quick service and support. 228964

Brakes work perfectly. Our rental trailer worked out great for an 800 mile round trip and 4 nights at a Florida State Park. We bought a used 20 travel trailer in February and have taken it on two short trips and a month long vacation. We have had no problems at all and now have almost 3000 miles of towing behind us. One emergency stop was exciting, but the rig stayed perfectly straight and probably stopped shorter than the Blazer would have done without the 4 extra brakes behind it. Thanks for all of your help and support.

I realy do not know where to start. 1) products and service were prompt and very curtious, but there was a major problem. 2005 tundra trailor hitch, break controller and wire harness. I first ordered and installed a trailor hitch on my truck. I needed the hitch for a tundra that had the drop down bumper with trailor ball holes drilled. Everything went as advertised. However it was necessary to use clips to pull the hitch to the frame to drill the aditional holes. 2. Here is the however. Before ordering a wire harness and controller I read the instructions on your web sight to determen if I had a tow package. I looked for the white plug behind and above and on the left side of the instrument panel to determine if I had a tow package. No white plug could be found. In all of my conversations with sells and letters to techneshions I said I had a 4 pin plug but no 7 pin plug. I had the step bumper with trailor ball mount holes but no white plug. Every one determined that with no white plug I did not have a tow package imstalled. I order a controller and the wire harness. I mounted the seven / four pin harness and the wireing from the rear of the truck to the engine compartment and mounted the fuses. The next day I removed the instrument panel lower trim and the air duct and begin to look for the wiring harness and the grommet in the left side of the firewall to rout the wireing into the cab. I looked and felt around the wire bundles and felt the white plug taped with black electric tape on the outside of the wire bundle. It was impossible to see the white plug even with the trim panel and air duct removed and black tape installed over it. After looking at other web sights I learned that if I had taken the VIN number to the parts department of the Toyota dealer I ould have learned that I had a tow package. If I had known that I had the tow package I would have ordered the upgraded brake controller with the less expensive wire harness. Johnnie Reaves 335964

IT WORKED PERFECTLY. This is my first time to purchase, install, and use a brake controller. Add to top it off, it was my first time to pull a trailer. It was on a Saturday, exactly six days before a scheduled tent-camping trip, when my wife found a good deal on a used pop up camper. The camper was equipped with electric brakes, so it was required to install a brake controller on my SUV. It was Sunday (next day) when I ordered the Tekonsha TK90160, along with the other necessary part numbers #118449, #A0500, #18136, #ETBC7. I was planning to take the parts to a shop to have it installed as soon as I received them. I was hoping I can get them on Tuesday, but UPS dropped it off to the local post office, which caused it to be delivered at 3pm on Wednesday afternoon. The shops that I went to either did not have an installer available, or were all booked for the week. I had to "take courage" and install it myself. I am so thankful that etrailer.com provides extensive videos of reviews, installation, and operation of the products that they sell. I made the connections as shown and hoped for the best. I picked up the camper on Thursday, and was sooo relieved that it worked perfectly. We took off on Friday and the camping trip was a success. We are looking forward to making more good memories with our camper. Thank you etrailer! 276385

Worked great on our two hour trip coming home from the R-Pod dealer. Good paper instructions. The video on U-Tube was helpful when drilling through the fire wall. The Toyota factory harness for the 2011 Highlander gives you no brake wire access, made worse by a knee air bag. After dropping the lower dash panels I was able to insert a flat bladed electrical connector into the back side of the plug going into the brake light switch and zip tie the connection in place. The Universal Installtion Kit ETBC7 is worth evey penny and makes the installation professional. The ETBC7 plugged into the existing four pin trailer plug and completed connections to the vehicle's battery and controller. Two suggestions: 1- The TK90160 should come with longer pig tail leads to reach the brake light switch (I added 4"). 2- The ETBC7 does not come with a plastic wire protector for the fire wall entry point. 469662

Installed this in my 2018 Tacoma TRD Off Road. After removing the sill trim and Kick plate to find the Factory Plug. I took the Bottom left dash down (3 Bolts) and some clips to gain access to the small cubby on the left of the steering wheel. Popped it out, trimmed it to fit with my Dremel and held the Unit in place with 3-M automotive trim tape. I only had to cut the sides of the cubby and a square hole for the plug to the unit. Looks Factory installed. All in all it took a couple of hours to do. my truck has only 135 miles on it so I was extremely careful. As you can see by the pics it's not in the way at all. It could also be put in the center console but it has a wireless charger and I didn't want any Electronic interference or block access to my coffee cup holders. 490872

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

Thanks Patrick for the follow-up. The brake controller, for the camp trailer, installation went relatively easy and operation of the unit continues to be great. More importantly is your product follow-up for Customer Service...providing a r-e-a-l name vs. Customer Service dept. along with a phone number and email contact information all pretty rare in todays environment. E-Trailer continues to be my first-source for product information search.

Primus Iq Brake Controller installed in a Mercedes Benz 2017 Sprinter. The van's electronics interface with the Primus, and it can detect when the trailer brakes lock-up, which lights an dashboard indicator lamp. I used the Mercedes-specific plugs under the driver's seat and ran the cables through the battery box to the dashboard. 489003

Just wanted to follow up with you. I have an old 2004 tundra. I got rid of a 3 year old 3500 Chevy and got in that 04 tundra. I have had a goose neck hitch and pull a 24 ft. With a dove tail, 3 beam trailer with that tundra. I have always had e-brakes, but had a used controller which I had wires spliced into place for the controller. I pulled that trailer for 10 years with that tundra and never really felt comfortable with the e-braking system. I kept that tundra kicked in the ass for 10 years with the loads I pull and was always on caution due to my lack of confidence in the braking system of that setup. We'll, I bought your controller and factory ready quick connect wiring harnesses for my make and truck model. We'll let me tell you that I have never felt so confident pulling a trailer in my life as I do now with the flexibility and control I have on my E-braking system now. I'm still up in arms on deciding wether this is better advertisement for you and the breaking system with the quick connect wiring harness, or better advertisement for the 10 year old tundra that I have always had and continue to kick in the ass with loads that onlookers shake their heads at when they view the work that my 10 year old truck and e-breaking system handles. This new e-breaking system allows me to have the confidence that I can control the velocity of the load I'm hauling with ease. Thank you. 150117

This will be more of an overall etrailer review as opposed to a specific product review as I've yet to actually test the product. So, you might ask, how can I feel confident enough to review a company whose product I have not tested. The answer is simple and solid...I, in all actuality, tested the very fabric of etrailer itself; their employees (specifically Bill and Kristin, my many kudos to you both). I tested their patience. I tested their gumption. I tested their resilience. I even tested the very foundation of their courtesy. With my innocently incessant questions, concerns and over-dramatizations, I pulled, tugged and prodded at the very essence of, what I can only assume is, their corporate ethic. I begged, probed and, most likely to some extent, annoyed their customer service with email after email for days; although, I'm sure to them it must have seemed like an eternity of overtime. Not once, was a single one of my inquiries met with even the slightest hint of aggravation or delay. If you think that I'm just touting because I love talking, you're sadly mistaken. Never in my long years have I ever "reviewed" anyone or anything online. I don't Facebook. I don't Twitter. I don't even go to the customer service desk at the grocery store. It's not my style and it probably never will be. But, I would feel remiss if I let this one go. There is a reason why their site comes up so frequently when searching for answers to new questions and available products...their company is clearly founded on successful ideals and, every effort of their service department proves it beyond a doubt. In the end, this old man was wrong. And, I suffered them through an unnecessary ordeal. But, I've come to find, that, in life, we get tested, often when we least expect and even more frequently, without knowing why. I can not say that there is a better reason for the tribulation they so positively endured other than to give me the confidence to proceed. But, then again, as customer's, is that not but what we seek. I sought affirmation and reassurance that I wasn't just shoving my money into a machine but, instead, shaking hands with an old friend. I was not disappointed. And, I doubt that you would be either. In fact, in my humble opinion, I believe that you'd have to be downright incorrigible to meet any dissatisfaction with their service. In an online generation where almost every site has almost every thing, and all at pretty much the same price, I can see no excusable reason to overlook the absolute value of total confidence in your purchase. The fact is, that at some point, I will need to order something for or have a question about my RV again, and every time my browser search shows results from etrailer.com, I will go their first because I have the experience to know that they know that the way they treat me will bring me back. 474860

I sold the vehicle but kept the controller and my new truck has the factory brake set up. I need to get the wiring harness for it as I left it in the vehicle. Ill get around to it one of these days and probably end up selling the controller. Its a good unit and worked like a champ. Which reminds me, I was going to buy some LEDs for the trailer. On the list for this winter I guess.

This is a great controller, recommended by my trailer manufacturer. I actually don't know too much about it, how it works, etc. But it doesn't require much knowledge to use it. Install it like instructed by etrailer it just works. You can see the number goes up as you apply more pressure on the brake pedal, and the trailer stops with no problem. It's magic. The only thing I wished they do is to supply a longer length of the thin wire to connect to the break line. For my 2013 CRV, the break line you need to tap into is on the left side of the steering column, if you want to install the break controller on the right side, the wire is a little so short; but you can make it, it's just a little tight. I want to install the break controller to the right side of the steering column because I don't want to accidentally bump into it every time I get in and out of the car. It's a great, the best product though. 450595

installed on a 2009 F-150 everything was as advertised. It was plug and play. My truck had the wire plug behind the dash so was easy to hook up. I installed it in the hole below the coin holder. To reach the pre-wired plug you have to remove the panel anyway. I don't like any wires showing or anything I might hit with my leg. So did not mount it on the lower dash. You have to pull the plastic box out to unplug the connector. So just cut off the back of the box off and run the connector through the hole and connect to the controller. This way you can remove the controller anytime you want. Also you can see the readout much easier then mounting it on the lower dash. See pics 333618

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

Just received and installed the Tekonsha IQ TK90160 on my 2017 Chevy Colorado. Thanks to your very detailed videos and the fact that my truck has the factory tow package the installation was a simple process. Chevy didn't label the wires but your video did a great job of doing so. Good job guys!!! 571385

  • Recommended Brake Controller for 2012 Toyota Tundra Crewmax 4x4
    For a brake controller, I usually recommend the Tekonsha Prodigy P3 # 90195 because it is a great controller that is easy to use with its LCD display. Because you don't need anything fancy, I recommend a similar unit in the Primus IQ # TK90160 which will have many of the same functions in a more traditional format. Either one is a proportional brake controller allow the trailer brakes to be applied at the same time and with the same pressure as you hit the brake pedal in your Tundra....

  • Trailer Brake Controller Installation in RV Built on 2015 Freightliner Chasis
    There are several different Freightliner chassis types used for RVs, such as the popular XC-series that is often used for Class A diesel motorhomes. This chassis can allow for plug-and-play installation of a trailer brake controller such as the Tekonsha Primus IQ Trailer Brake Controller # TK90160 so long as the RV has a factory tow package. In this case you will use wiring adapter part # 3027-P to connect the Primus to the under-dash port. This adapter also fits 2004 - 2015 Freightliner...

  • Installing a Tekonsha Primus IQ Brake Controller on 2019 Subaru Ascent
    The photo you sent looks like it may be what you need to hardwire to the Tekonsha Primus IQ Trailer Brake Controller # TK90160 to as a step of the installation. To install this brake controller in your 2019 Subaru Ascent without the factory tow package you need to start by adding a 4-way, the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118790; I have added a link to an installation video of this connector on a '19 Ascent for you to take a look at. You will also...

  • Brake Controller Recommendation for 2018 Ford Transit E250
    For a brake controller for your 2018 Ford Transit T250 I would recommend the Prodigy P3 Brake Controller part # 90195. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes. This will be the last brake controller you buy. It can easily be transferred to future vehicles as well. There...

It features an easy-to-read LED display with continuous diagnostics to alert you of any potential issues and 3 boost levels that let you fine tune your braking aggressiveness....

To use the Tekonsha Primus IQ Trailer Brake Controller # TK90160 with your 2019 Chevy Silverado 1500 that has the factory tow package you will need the Plug-In Wiring Adapter for Electric Brake Controllers # 3064-P in order for it to get power.

  • Is Separate 20 Amp Fuse Required When Installing Brake Controller on 2018 GMC Canyon
    Since your 2018 GMC Canyon already has the needed brake controller wiring ran up under the dash (which indicates that you have the factory tow package), a separate 20 amp fuse isn't needed when hooking up a brake controller like the Tekonsha Primus IQ # TK90160. As you mentioned, a 30 amp fuse is already installed in-line on the truck for this protection. The pigtail wiring from the controller will splice directly to the wiring under the dash. On the brake controller the blue wire is...

  • Out-of-the-Way Brake Controller Recommendation for 2012 Toyota Tundra With Factory 7-Way
    The Prodigy P3 # 90195 or P2 # 90885 are really great brake controllers, but to mount them out of the way so you don't have the unit hitting your knee or in the way under the dash you may need to splice together two of the Plug-In Wiring Adapters # 3040-P, as I'm not exactly certain what the length you need is to mount the controller where you are wanting. These adapters are 32" long, which should tell you if you need to get a pair of them or if they have enough length for you to mount...

    Absolutely! It sounds like you already know what you need but are looking for the easiest to install products that have the best value.

The installation process for this harness will be the same as the other options we have for you but we find that Tekonsha brand wiring products tend to be the most reliable which is why I recommend this for you.

  • Adding Trailer Brakes to a 3.5K Dexter EZ Lube Axle and Brake Control/7-Way on 2016 Subaru Outback
    The brakes you have chosen, # 23-468-469, are compatible with the hub and drum assembly # 84556UC3-EZ and those assemblies will fit the Dexter 3.5K EZ Lube axle.

  • Which Value Circuit Breaker for Installing Primus IQ Brake Controller TK90160
    When hardwiring a trailer brake controller like the Tekonsha Primus IQ # TK90160 either a 20-amp or 30-amp circuit breaker will provide operating power for the controller itself. The choice depends on whether the trailer has one braked axle (use the 20-amp value # PK54520) or if it has two or three braked axles (use a 30-amp breaker # PK54230). The breaker should be mounted on the firewall, reasonably close to the battery positive terminal. The copper-colored terminal on the breaker...
