Tekonsha Brake Controller - 39523

Easy-to-use brake controller activates your trailer brakes electronically when you engage the brakes in your tow vehicle. Set braking intensity to your preference and towing application.


  • Brake controller activates electric trailer brakes (sold separately)
    • Signal is sent to trailer brakes when tow-vehicle brakes are activated
  • Adjustable output control lets you determine the amount of braking force
    • Set to maximum when you travel through hilly terrain with your fully loaded trailer
    • Back off the power output when you tow a lightweight trailer
  • LED indicator on front of unit
    • Green light indicates that brakes are connected
    • Color changes to orange and then to red as the power output increases
  • Built-in manual override
  • PowerTrac can be used with trailers that have up to 2 axles (4 brake assemblies total)
  • Mounting bracket and hardware included
    • No need to mount level
  • Additional pigtail harness (sold separately) is required for complete installation
    • For some vehicle-specific applications a plug-in, vehicle-specific brake-control adapter (sold separately) can be used to further reduce installation time


  • Dimensions: 3" wide x 5" long x 1-1/4" tall
  • Limited 5-year warranty

Unlike pendulum-style controllers, which react to the inertia that is created by your tow vehicle slowing down, the PowerTrac applies your trailer's brakes when the brake pedal in your tow vehicle is engaged. The trailer brakes will be activated with an intensity set by you. This output (amount of braking power) is adjustable to suit your preference, as well as road conditions, type of trailer and load. You can also apply the brakes manually with the integrated override.

Because inertia plays no role in the functioning of this controller, you do not have to mount the unit at any particular angle. As a result, mounting options are nearly limitless. After mounting the unit, hardwire the end of the pigtail harness (sold separately) directly into your vehicle. For even easier installation, a vehicle-specific wiring adapter (sold separately) is available for certain vehicles. One end of the custom adapter plugs into your vehicle, and the other end plugs into your controller - no hardwiring required. To transfer the PowerTrac to another vehicle or to remove it for storage, just unplug the unit and remove it from the mount.

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: For vehicles without brake-control wiring adapters, a 20-amp circuit breaker (9506P - sold separately) is required.

See also etrailer.com's exclusive 7- and 4-way brake-control installation kit (ETBC7 - sold separately) that includes all the parts necessary to install the PowerTrac brake controller.

Video Transcript for Tekonsha Brake Controller 39523 Review

Today we're going to be reviewing part number 39523. This is the Pro Series PowerTrac Electronic Brake Controller for trailers with one to two axles. This is a time-delayed brake controller. It's going to activate the electric trailer brakes. A signal is going to be sent to the trailer brakes when the tow vehicle brakes are activated or when the manual override is activated. It's also going to feature the adjustable output control that's going to let you determine the amount of braking force. All you've got to do is use that thumbwheel there to decrease it or to increase it.

You want to set it to a maximum when you travel through hilly terrain with your fully-loaded trailer and then you can back off the power output when you tow a light-weight trailer. The little circle down here is going to be the LED indicator on the front of the unit. It's going to show green, which is going to indicate the brakes are connected. Then the color is going to change to orange and then to red as the power output increases which we'll show you that here in a few moments. Its got the built-in manual override. The PowerTrac can be used with trailers that have up to two axles which would be 4-brake assemblies total. The mounting bracket and the hardware are all included.

There's no need to mount this level. You can actually swivel it a little bit inside of the bracket. Additional pigtail harnesses are going to be sold separately or plug-in vehicle-specific brake controller adapters. Those are going to be sold separately as well that can be used for certain applications to further reduce installation time. Well go over the dimensions of the actual brake controller. It's going to give us a width of right at 3 inches and then an overall length of 5 inches and it's going to stand about 1-1/4 inch in height. The PowerTrac is going to apply your trailer's brakes when the brake pedal in your tow vehicle is engaged. Those brakes will be activated with intensity which would be set by you using that thumb dial.

The output again, is adjustable to suit your preference as well as road conditions, type of trailer and whatever kind of load that you're carrying. You could also apply the brakes manually, again with that integrated overrride system. Please note that for vehicles without brake control wiring adapters, a 20-amp circuit breaker is going to be required. You can find that here at etrailer.com with part number 9506P. That is going to be sold separately. You can also check out etrailer.com's exclusive 7- and 4-way brake control installation kit, part number ETBC7. That's going to include all the parts that are necessary to install the PowerTrac brake controller. We are going to go and hook it up to our power source.

That way you can get an idea of the indicators and the LED that I was telling you about. Once we have that connected, go ahead and turn it on. The LED indicator is going to lighten up and that's going to show a green indicator signifying that we are connected correctly to our application which would be to our trailer and in this case, it's our external power source. Then you can see here that we have the output level to control the intensity in which our brakes are applied and then it's also going to feature the manual override. As I slide that over, the light is going to change color. It's going to go from a green to an orange to a red and then backing off and letting go, it's going to go back to that green indicator that is going to signify that everything is connected correctly. More than likely you're going to have it installed under your dash in this position here. It's got a nice flat surface so that way it can be angled to accommodate a lot of different situations or applications. The mounting bracket's going to go over this portion here and the mounting bracket has this little slot here that's kind of a little C-channel shape. That's going to allow it to pivot, so you are going to be able to change the angle to best suit your application. It's got the bracket. It's got all the screws needed. All you've got to do is screw it in to the surface that you want and then attach it to the brake controller and it's going to be fully set and ready for use. That's going to do it for today's review of part number 39523. This is the Pro Series PowerTrac Electronic Brake Controller. .

Very easy to install and looks great in the truck, only wish i would have ordered the pigtail that goes to the truck. 26397


I ordered this brake controller for a 2003 Nissan Pathfinder with Universal Installation Kit. Not an easy job since theres no factory harness to plug the controller into. As others have said in the reviews the hardest wire to connect it the red one since it connects to the cold side of the brake pedal switch.There is literally an inch of space and little to no slack on the brake wire plugWhich is the black one on the right with 3 green wires with stripes and a red wire. . The brown plug is the shifter release switch. This was the hardest part of the whole install. The wire and plug was nearly impossible to get to or see. I had to lay on my back and twist sideways with a utility light next to my head shining under the dash. I cut my hand up pretty good getting the white plug disconnected from the black brake switch before I tapped it. The lock on the plug is above the steering wheel shaft so you cant see it or get pliers on it. I had to do it by feel and press with all my might with my right hand and pull the plug out with my left. The wires are covered by black rubber sheath which you have to slit back to the harness before you can tap it.The wire you want to tap on a 2003 Nissan Pathfinder is the GREEN wire with a YELLOW stripe. Once I tapped into that wire I double checked by unplugging the harness from the brake controller and using the LED tester. I clipped it to the metal surrounding the brake pedal, pushed the probe end into the red wire connector on the harness and pumped the brake pedal and the LED lit up!! So I knew I was successful.The rest was easy running wires to the battery and the connector on the back. The other small problem was the 10 gauge duplex wire included with the universal installation kit was literally a few feet short to reach the battery so I had to buy a roll of black 10 gauge at the auto parts store to complete the installation.Ill let you know how it works with the Pontoon Trailer!

We have a Honda Ridgeline and needed this for our camper trailer. It was nice ordering the specific plug in wire for the Ridgeline and therefore eliminating hard wiring, just plugged it in. It was rough getting to the factory plug under the dash by the emergency brake petal switch. My hands are not small enough, ha ha. But success was had. Plugged into the controller and mounted it and u-wall-a. It works the way it is suppose to, I like that. A good quality unit that does what it is suppose to. thanks. 202036


After a year, I dont even think about it being there. I love that. It works the way it should. When traveling with our trailer, I might adjust the controller slightly but that is it. . . .thanks etrailer and Tekonsha for such great products and service. . .you rock. . . .jim

This review is for the Tekonsha PowerTrac Electronic Brake Controller - 1 to 2 Axles - Time Delayed. I installed this brake controller on a 2014 Jeep Unlimited and at the same time installed a 7 way trailer connector. I bought a Jeep factory harness for the 7 way connector so that was just a simple swap out of the factory 4 flat connector. This ensured that I had working lights while I worked on the install of the Controller. The Jeep harness included the wiring for the trailer brakes so I just had to install the Controller and the wiring for the controller at the engine end. This took about 4 hours. I didn't own a trailer yet at that time so I took the Jeep to a local trailer rental place and they tested the install for me. It worked. They also explained to me how to use the controller. I later bought a small travel trailer and the dealer for the trailer tested the install of the Controller and explained how to use it. By this they meant how I adjust the sensitivity of the controller. This they explained was best done by setting the sensitivity to zero (thumb wheel on controller) and then while pulling the trailer adjust the sensitivity up until some 'drag' is felt and then backing the sensitivity back down just until no 'drag' is felt, and that's it. I don't know if the manufacturer would agree with that. Their documentation did not explain exactly how to use the controller. Now that I've used the trailer a few times and I go through this I am comfortable with it and I feel the Tekonsha is providing the the control needed for safe towing. 210105

Great price. I used this unit, made by Tekonsha, to replace a Tekonsha Prodigy unit that was (3.) times as expensive. (It lasted (4.) years. The green LED lighting was no longer visible. Therefore, making the unit inoperable.) I installed this unit in a 2012 GMC Sierra 1500 pickup truck. The truck had the wires for a trailer brake controller under the dash. All I had to do was pulled them down. This is how I connected the wires: Small blue & white wire on the truck to the blue wire on the trailer brake controller. Small white wire on the truck to the white wire on the trailer brake controller. Large blue wire on the truck to the red wire on the trailer brake controller. Red/black wire on the truck to the black wire on the trailer brake controller. I mounted the trailer brake controller to the right, and at the very top of the pullout ash tray with the screws that came with the trailer brake controller. I am right handed, so this location allows me to see and operate the trailer brake controller with my right hand while resting my arm on the fold down storage area/beverage holder in my work truck. E Trailer is a good company. Their prices are fair and they have an excellent customer support system. If you have a question or a problem they are there to take care of you. So I don't shop anywhere else when I need something that they sell. Why would I? 329265


Thanks for your review and your business, Rick! Often, the color of the wires are determined what wires the factory uses on a particular run, so we always recommend testing for function by using a wiring tester, such as # 3808.

Easy to install in my Toyota-Tacoma 2012. I pull my Travel Trailer and this break controller worked very well and with just a little bit adjustment. Also this item was shipped very fast. 89077


I just installed this on my 2010 Tacoma, which was very easy. I hooked up a new trailer and I noticed right a way the brakes seem to pulse. You can see the LED flicker between red and green that appears to be synced with the brake pulsing. Does yours behave similarly? This is my first trailer and brake controller so Im not sure if its normal or not.

-- comment by: Quincy - 04/02/2014


That is not normal operation. There are two likely culprits: First, a weak or loose connection to the brake switch wire. Double check that first so the controller can positively know when you are applying brakes in the Tacoma. Second, Toyotas are known for finnicky electrical grounds. If you didn't when you installed it, run the ground wire for the controller to the negative terminal on the battery. If it is grounded to the body, the controller may not be getting sufficient ground so the brakes start to engage and the ground cuts out, and it does this over and over resulting in the pulse.

Now after one year Im using the same brake controler in my new Tundra and still working very well.

I have a Toyota Tacoma (06). I had the controller installed in less than five minutes. One minute to gather the tools: drill/bits, screw driver, and tape. I thought tape would be helpful to hold the ground screw to the driver given the tight are under the dash. One minute to drill the ground hole. One minute to install the ground screw. One minute to plug in the cables and fish the wire under the stirring wheel to allow for the controller to be mounted in the storage area found on Tacoma trucks dash. I guess I was wrong. It only took four minutes. I did not need to put the tools away I was off to do other projects. I rate the product as good because I have not tried it on the trailer yet. 86205


Today I used the controller out on the road, it worked great. Now I give the product a SIX star rating. Its better than a five star rating because of the reasonable price and installation of the product. Good job etrailer. Mike from Santa Fe.

-- comment by: Mike L - 06/29/2013


We can't take that much credit, you performed the install. Glad it proved to be a quick, easy and worthwhile project, and thanks for coming back to give us an update after you tested it out. Happy towing!

The control works great. Nice incremental application of wheel from nothing to hard on! Led light goes from green to red also in incremental degrees. Installation was a snap in my 2008 F150 with tow package. Just Plug in the control clip and the other end in the terminal above and to the right of the computer check terminal. Rather than have it below my dash I opted for the cove below the lighter. Etrailer did a nice job of getting out to me right away and kept me informed where this was at all the way to my door. Good Job! 79780

Just got done installing this brake controller on my 2011 Tucson. It was a whole lot more difficult than everyone says. It was not the product; very nice unit which installed nicely under the dash. The unit only has 4 leads, 3 of which were no issue. All 4 wires had to be extended (understandably). 3 out of the 4 snaked nicely into the engine compartment. I just widened the existing wiring thru grommet going thru and these 3 slid right thru. Black (Hot), White (Ground) and Blue (Output to trailer brakes). What was the bear was the Red lead which connects to the output side of the brake light switch. When I crawled under dash I could not even see this switch. I could only feel it let allone conect a wire to it. The only alternitive I had was to slice the main harness open (still very hard to get at) and then 1 by 1 find out which of the 40 wires had feed when the pedal was depressed. Once I found this, it was still incredibally hard to get a splice on this 1 lone wire. This is not the products fault; it is just the way they engineer cars these days. All in all the product is great! Gary H. 67561

I received my purchase very quickly. I just installed the control and wire harness today. Installation was easy, all you need are basic hand tools and a drill with a small bit. Haven't had chance to test it out yet but, when I do I'll update. 388664

For the price, it works good. If you haul far distances, or do it frequent with heavy loads (5 ton in my case) this may not be ideal and you really need the more expensive units that relate braking to lean of the vehicle or brake pressure applied. Some reasons why I say this are... You need to turn it off every time you back up if you plan to touch the brake at all or your trailer brakes will apply and prevent you from backing up. Keep further stopping distances, as the braking force is either too fast, or too slow, never perfect depending on how the sensitivity is set...I find you must pulsate the brakes with a heavy load if the trailer brakes are set high. If you don't do this, you are running your trailer brakes too much to stop the truck, or too little a deposit the truck is stopping the trailer. We use this in our 99 F250 Powerstroke towing a 10,000lb trailer often from PA to NC down the Appalachian. 338447

Small, easy to mount and easy to install. I purchased the pigtail that goes to my truck and it took me longer to pull out and put away my tools that it did to install the unit, it's no bigger than a radar detector and had it adjusted in under 5 minutes. Went for a short ride while towing the trailer and adjusted to proper setting very easily. 135946

Install was easy just as etrailer said. Product works great for a 2 axle trailer. I mounted it to the coin holder door left of steering column so that the screw holes would be in the plastic door, which I could replace if needed. Routed wires under hood release. Great company! 95444


Works great no problems. Thanks for the follow up.

Received my controller today and it mounted easily in my Nissan Frontier with the adapter that plugged right into my wiring harness. When I got it mounted I found that the light did not come on. I went on line to the question and answer section of etrailer.com and found that it had to be hooked to the trailer for the lights to come on. I drove to the storage facility where my RV toy hauler is parked and when I hooked the light cord up the light on the controller lit right up. When I bought the trailer I had to quotes of more than $250 to install a controller and then I looked further on line and found etrailer.com and saved myself about $200 in the hour it took me to install it and hook it up to the trailer. My experience with etrailer.com was great and I will continue to check them for further needs. 412452

The brake controller was completely installed in less than an hour and worked perfectly. The most valuable piece of my order was the free video, which showed that even with factory trailer wiring, and the controller hooked up properly, there was still some work to do under the hood. That is, removing the brace that covers the fuse enclosure and pulling off the enclosure to expose two wires that must be hooked to studs and two blue wires that had to be connected to each other. After that, installation of a five dollar 40 amp fuse in place of a dummy fuse in the fuse array. Who knew? The last controller I used was a pendulum type. This new all-electronic model is clearly superior. Thanks. Headed to Florida next month. 286075

I ordered the powertrac with the 22292, 2011 ford F150 wiring adapter, It works great. 15 mins, and I had everything ready to go. It is a little sensitive to adjust but ones you get the feel for it, it takes no time to adjust. very happy with this unit, I would recommend this unit to everyone. 380737

Excellent product. This trailer controller plugged directly into the factory Ford F250 wiring. Works excellent. Recommended if you like having an adjustable type of controller. I like being able to make some trailer brake adjustments depending on the load I am towing. Great design. Will buy again!! I use this with a 14k trailer towing everything from backhoes to cars and it works great. I can add a little more grab depending on the weight behind me, and it is very easy to adjust on the fly- a little too much, back it down a bit with the dial. Easy as can be! Thanks eTrailer for the fast service and great products. Have been using this for a little over 1 year and it works like new. 319818

The device itself works as advertised. No problems with operation and adjustment super easy. The mounting bracket required some thought to install. For my installation it was difficult to reach and get any pressure on the screws that attach the bracket to the controller. Had to use a 1/4 inch closed end wrench under the dash. I pre-drilled the holes but had to loosen them to slide the bracket away from the center console to reach those screws. It was awkward at best and took quite a bit of patience and was by far the longest part of the install. SO, I would recommend a rethinking of the bracket design by the manufacturer. Certainly this was not any fault of etrailer. 211287

This is the same controller that I have in my motor home. Installed this in my 2008 LWB Nissan Titan 4X4. After reading a review about taking the lower dash cover off, I removed 2 screws at either side of the bottom of the panel and gently worked out the other clips took about 2 minutes to remove and found the electric brake harness tagged - added the new vehicle specific harness adapter (sold separately) put the panel back and mounted the controller. Took about 15 minutes. e-trailer folks rock! 280133

I purchased the wiring kit, brake controller and extra bracket for my 2016 Promaster 118. The install went great. I used another stainless steel bracket to attach the 7 way to the bumper cover. It looks good and totally professional. The brake controller sits just below the fuse box and is out of the way but accessible. I did route my power wires going to the front beneath the van. I drilled a 1/2 inch hole through the rear plastic of the battery box to bring those wires in. 302828

Pretty easy to install in my 2003 Toyota Sequoia, I got the factory wire harness and found the connector under the dash, had to remove a white plastic empty connector then plug the one that came with my brake controller, hooked up to camper and tested it, green light came on and turned a little orange when I applied the brakes,didn't go for ride but heard electric brakes when brakes applied so seems like it works. Happy with purchase! 378485

by: David E04/12/2017

Overall this is a great product for the money for small/medium rigs or if you don't tow on a regular basis. Installation was quick and easy. It does not fine tune real easy and is easily affected by weight change. It's perfect for my use, which is a 17' toy hauler. Anything bigger and I would go with a unit which had a gross adjustment and then a fine adjustment, which I have had in the past, when I regularly pulled heavy loads. 366149

Installation went very smooth in a few minutes with the Ford wiring part i ordered here at same time. I have only tested that it has power and lights operate when hooked to trailer. I have not road tested unit yet but I have no doubts. I installed in the slot under the steering wheel so it is flush/recessed with the dash so I dont hit my legs on it everytime getting in and out of vehicle 187456

I had ordered a wiring harness for a electric brake controller, Pod brake controller and a Pollack Trailer connection socket with a 7 and 4 connection plugs. Items came quickly and had all items installed in less than an 1/2 hr. on my 2016 Silverado truck LT. it took only a screw driver to complete the job. Well Done etrailer for your parts and shipment. I will be a returning customer. 363801

Can't tell you about the product I purchased it for evacuation of my horses only (which hopefully will not happen). It appears easy to install and use that was the reason for purchase. Etrailer was great everything was handled exactly as stated. Prices (better than ebay), customer service, website and videos provided are great. I will be using etrailer for all future purchases. 191135

The product was easy to install. The etrailer.com question and answers, plus the online instructions available prior to purchase there were no surprises. I received the product within the time indicated. The quality of the product appears consistent with the description. The added cutomer service on the web page is what made up my mind. No complaints will see how it holds up 57858

Exactly what I needed. Works well, priced right, and easy to install. It probably took more time to decide where to mount it than to actually install: two screws into the lower dash to hold the bracket, plug the supplied harness into the factory connector under the dash, and connect the unit into the bracket. Definitely helps when towing a heavy trailer through hilly terrain. 409292

With the recommended adapter install was a snap. Only thing I had to figure out was how to get 12v power to the 7 plug. Turns out I just needed to install a fuse in the fuse panel under the hood. FYI the stud 1 socket on a 2000 Suburban with factory 7 plug. Hooked up the trailer and followed the included directions and everything worked great. Couldn't be happier. 276267

Very happy with my purchases from etrailer. I chose standard shipping (5-7 days) because it was free for orders over $150, but to my surprise my entire order came in 2.5 days. All the products were exactly as described and exactly what I wanted for my new trailer. Also after a lot of research etrailer had the best prices and name brand products that you can trust. 94182

Installed using wire and connectors bought from etrailer.com as well. Simple to install and it's working beautifully. Everything about this was great from the price to the product to the delivery to the instructions on installation. Couldn't have asked for a better experience. I'll be back for any and all of my trailering/towing needs. Thanks! 157181

Unfortunately, I have not installed this unit yet. It appears to be a very nice little electronic brake controller. My problem is that this was suppose to be plug, and play, but my vehicle did not have the trailer plug per-installed. At this point I will have to have my mechanic do this. Too many wires and no schematic for vehicle wiring. Oh well... 294067

Not being mechanically inclined, I found watching etrailer.com videos BEFORE I purchased a great help. Also, my purchase experience with Michelle S. was amazing (friendly and knowledgeable). As advertised, the product was as easy to install as "plug and go"...... Moreover, the instructional videos were of GREAT assistance1 Thanbk You etrailer.com 265182


AMAZINGLY!!! In fact, you wont want to hear thisbut, I use a single unit interchangeably with two tow vehicles. SO EASY to install. Thank you again, for a GREAT product.

This came quickly, but is not installed due to the other end of the plug is sold separately. You may want to remind us in you description. The video was a big help for the install of the wiring I got with this and it did say the part was sold separately If there are no problems after I get running, over all I am very happy with finding etrailer. 154514

I bought a Tekonsha PowerTrac Electronic Brake Controller (POD) Pro Series. It fully meets all claims and specs. It was very easy to install and works perfectly. It is very easy to set up and operate. I like the size of it also, it is smaller than many other units I compared it to. I use it on a 2 axle trailer with a gvw of 10,500 lbs. 367055

The web site was easy to use, the price was affordable and it arrived within 10 days of ordering.

Once the plug was found it took less than twenty minutes to install. Thanks eTrailer!! 304654

The controler did not work, no matter how I tryed to hook up the hot end of it. Also the adapter is NOT the same as the one that came with the truck.

Being able to acquire a whole breaking system (soup to nuts), wire, fittings, fuses, conduit....etc is a great benefit. Even better, there are presentations on the web site which show the steps of installation on your type of vehicle. Outstanding project sales and presentation.

This is my second brake controller from etrailer. Sold a vehicle and needed another. Super fast shipping and exactly what I needed. Went in without a hitch due to detailed video. Love to send pic, but it's a black vehicle with a black controller and wire. Blends nicely, but doesn't photograph well. Great company! 363165

This was a replacement for a 10 year old item of the same type. The original went 1000's of miles and didn't owe me a thing. So glad I could get an exact replacement for ease of installation of the replacement. Just the perfect match for my 2-axle boat trailer which weighs about 10,000 lbs boat and all. 118293

Do you have a question about this Brake Controller?

  • How to Convert a Trailer with Surge Brakes to Electric Over Hydraulic Brakes
  • You can convert surge brakes to an electric over hydraulic braking system. To do this, you will need an electric over hydraulic actuator and a brake controller. For an electric over hydraulic actuator, I recommend looking at the Carlisle HydraStar units. If your trailer has drum brakes, you will want part # HBA-10. If your trailer has disc brakes, then you will want part # HBA16. I have also attached a link to all of our electric over hydraulic actuators for you to check out your options. The...

If your Silverado was not equipped with the factory 7-way, you can install the # HM40975 which would plug into the harness at the rear bumper. If you click the provided links, you can see some install...

  • Troubleshooting Sticking Electric Trailer Brakes
  • It sounds like your trailer brakes are sticking, but I doubt the problem is the brake controller. However, you can test this by applying the brakes like you normally do while coming to a stop. Once the trailer and vehicle stop get out and unplug your trailer connector. If the brakes release right then that would indicate that the controller is the problem. If not, get back in the truck and see if they release once you take off like they had been doing. If so, then the problem is not the...

  • What is the Difference Between a Time Delay Brake Controller and a Proportional Brake Controller
  • The Tekonsha PowerTrac brake controller # 39523 is a time delay brake controller. The other type of controller is a proportional controller. A time delay controller is so named because there is a delay between the time that you initially apply the brakes in your tow vehicle and the time that the controller reaches maximum power output. Unlike a proportional brake controller, which activates your trailer's brakes based on the deceleration of your tow vehicle, a time-delayed controller sends...

Using this adapter, you will be able to tow trailers with 7-way connectors or 4-way connectors. There are a few additional parts we used when installing this connector. When connecting to your existing 4-way connector, dielectric grease # 11755 will help to protect the connection. We recommend securing this connection with a zip tie and...

  • Availability of Brake Controller Harness for 2001 Toyota Tundra
  • If you are looking for a brake controller harness, there are none available for the 2001 Toyota Tundra. The 2001 Tundra did not have factory tow packages as an option, so a brake controller will have to be hard wired into the vehicle. You will need part # ETBC7 to create a 7 way plug at the rear of the truck. I will include a video on this kit. You will also need to install a 4 way connector. Toyota put the provision in for this so you will need part # 118378. Once you have these...

  • Will a Brake Controller Draw Enough Power When Not in Use To Drain a Car Battery
  • The brake controllers available now either are only on when they are activated, or a have a timed shut-off or idle state after a certain time period. Some of the older brake controllers never shut-off, but they did not drain battery power as the only component that would be on is a low amperage LED indicating that the controller has power or whether or not it was connected to a trailer. As long as you have a healthy battery, you should not have a problem. Since your car is only 2 maybe...

Between the trailer brakes and the brake controller there are several grounds that need to be checked. I will start at the top and work down one by one till we can find the source of the problem. Some of this may be redundant so bear with me. I assume you mean that the green light does not come on when the truck is on and the trailer is connected....

  • No Green Light on Tekonsha PowerTrac Brake Controller, Part # 39523, When Trailer is Connected

(Also, if you happen to have a breakaway switch on your trailer, take care that you do not ever test it with the trailer connected to the vehicle as this will damage the controller.

  • Troubleshooting a Tekonsha Powertrac Brake Controller # 39523
  • There should not be 12 volts coming out of your ground terminal (7:00) on your vehicle connector. That sounds like where your problem is located.

I attached a picture of how the connector on your tow vehicle should be wired by function for you to check out. I also attached an FAQ page on trailer wiring that you might find helpful.

  • Trailer Brake Controller Recommendation for a 2012 Ford Expedition with Factory Tow Package
  • There basically two types of brake controllers: time delay and proportional. Time delay controllers, like # 39523 that you have referenced, send back a pre-set amount of voltage over a certain amount of time which can be adjusted. It can take some time determining the best set up for any given trailer when using a time delay controller and there is more wear and tear on both the vehicle and the trailer. The benefit is that time-delay controllers do not have many mounting restrictions. Proportional...

  • When no trailer is connected the light on brake controller # 39523 will either be flashing or off. If it is green all the time with no trailer connected that indicates a short to ground. This normally occurs when there is corrosion on the pins or where the wires attach on the trailer connector. I have included a link to the instructions that include a troubleshooting section.

If you do connect a trailer and the light does not come on it could indicate a few different issues. First, check the black wire behind the controller for voltage. If there is no voltage going to the controller it will not turn on. You will need to check the fuses associated with the tow package to determine if something is blown or missing.

If you do not have a circuit tester, we offer one, part # 3808. Certain vehicles (like GM trucks produced in the late 1990s) had brake switch wiring that was very difficult to access. In those instances, we typically recommend doing exactly what you propose.
