Installation of Tekonsha Brake Controller Adapter

Junction BoxBrake-Control Adapter Port

This adapter plugs into the port that is built into the electric junction box beneath your vehicle's dash. The black box is located to the left of the steering column, just above the carpet. To plug in the adapter, first remove the cover on the box. The adapter plugs into the second slot from the left, on the top row.


To install your electric brake controller you need to connect the wiring of the controller to your vehicle. Certain manufacturers offer pre-wired options, typically known as tow packages, wherein these wires are run for you from the dash to the trailer connector on the back of your vehicle. Often, a brake controller wiring harness is included with your tow package. This harness plugs into a port beneath your dash and connects to the four wires of the brake controller. If, however, you have a brake controller with a plug in place of the four loose wires, you can use the Tekonsha adapter.


This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

Video Transcript for Trailer Brake Controller Installation - 2001 GMC Yukon

Today we are going to install a brake controller on a GMC Yukon, a 2001 model, and we are going to be a brake controller using part number 90185. And we are also going to be using adapter part number 22283. All right, we are going to mount our brake controller on the bottom of the dash. And there is a steel component that is going all the way across. We will go ahead and mount to that. What we will do is actually take the bracket, find a position we like, and go ahead and clamp it into place. All right, we are going to use some self-tapping screws instead of the screws that came with the kit it is a little bit easier to drill into the metal. The screws that come with it are actually designed for plastic.

All right, we have got our mounting bracket done. Now let us go to the port that is supplied from the tow package on the vehicle, which is behind this panel right here. All right, we have the box open, and you will see this row of sockets on the top here. We are going to use the second one from the left, this one right here. And our adapter plug will just simply plug right into it. Just push it in until it clicks, and then just put the harness off to the side, and reinstall the cover. All right, we have got our brake controller we just plug the two together. We have already got power going to it, so that is a good sign. At this point, we just go ahead and bolt our brake controller to our bracket here. Now we take our excess cable here and just zip-tie it to this piece of steel here. And then back and forth just to keep it out of the way of the pedals, and we will be good to go. All right, and with a few easy steps, the brake controller is installed in our Yukon. All right, and that covers our install of part number 90185, and its adapter cord, part number 22283, on our 2001 GMC Yukon.

Bought a new Primus IQ brake controller but it only came with a pigtail wiring that had to be spliced into my '01 Suburban. Ordered the direct fit wiring pigtail from etrailer.com and couldn't be more pleased! It literally took me less than 10 minutes to plug in the wiring and mount the brake controller. Excellent customer service and very fast shipping! The kind of shopping experience that causes repeat business. Thank you etrailer.com and customer rep Lexus for making everything so simple! 203301

1999 Chevrolet Suburban

etrailer's instructions and videos are awesome. installation was a breeze UNTIL I needed to locate the brake signal wire (cold side of brake switch) on my 1999 suburban. What a pain. the switch is not very accessible let alone there are a ton of white wires under the dash --along with an alarm. Long story short, I found this in a GMC forum and it saved me big time: "Under the dash, next to the emergency brake is a black convenience box. At the bottom of the box is the letters GRN, next to that is the letters NAT with a small recessed box with two male spade connectors. The spade on the right goes to the brake switch. The wire from the brake controller is terminated there." Using the supplied probe tester I was able to verify this and finished up my installation. The Tekonsha Prodigy P3 controller works great. 112192

The Tekonsha Prodigy P3 controller is still working great. I cant believe i didnt get one sooner. Easy to adjust on the fly and no issues at all.

2000 Chevrolet Silverado

Wasn't quite as easy to install as expected. Needed an experienced mechanical eye hooked to a limber body to find the right plug in spot under the dash. Some debate on where on the dash to hang the brake box, but I went with where the holes already were. Those teeny screws are tricky to get in and really did require a 1/4" ratchet, my fingers couldn't do it. Simple procedure, but did need the right tools. Took about 25 minutes, but some of that was going for tools... YES I'D BUY IT AGAIN ! One detail I learned about after installation, NO FUSE in the truck for it to work off. Needs a 40 amp fuse, and I didn't have one. Something to consider if yer new brake ain't working... sorry I do not have photo ability, if someone comes along, I'll ask them to take a pic. 662374

Fit perfect on my 2002 GMC Sierra. Installed in a snap. Cable is long enough to place brake controller anywhere under the dash below the steering wheel.

Plug did not work on my 99 GMC K1500 Classic. Only alternative was to cut plug off and hardwire. GM made two models in 99. The classic was the early model like the 98. The instructions were somewhat misleading. 638187


Comments

1999 was indeed a split model year. GM produced both the C/K series and the Silverado. The C/K series was mechanically unchanged from the 1998 model. GM did not have the under the dash plug for a plug and play brake controller until the 1999 Silverado. The 1999 C/K series would need to be hardwired like the 1998 model. In our fitguide, we show both models.

Hello I hooked it up and it will not power up, any suggestions? 588610


Comments

If your 2002 GMC Sierra does not have a factory towing connector you will need to finish the wiring for a 7-way plug at the rear of the vehicle. If you have a bundle of wires at the rear of the vehicle you will need part # PK11898
Pollak 7-Pole, RV-Style Trailer Connector Socket w/ Wiring Harness and Mounting Bracket
$87.44
. If you have a plug at the rear of the vehicle with a cap you will need part # 30955
Replacement Custom Multi-Tow 7-Way and 4-Way Trailer Connectors
$45.41
instead of the PK11898. If your 7-way plug is already wired in and you still do not have power you probably need to activate your towing package by connecting two power feeds to your fuse box. These two power feeds are located under the hood and they will need to be connected to two posts in front of the battery. The first power feed is located on the wiring harness that runs below the brake master cylinder and booster that will need to be connected the post on the battery. You can locate the next power feed in a wiring pigtail between the fuse box and the inner fender well on the drivers side that will need to be connected to the post on the battery. I have attached a video please skip the brake controller installation until you get to 3 minutes 45 seconds in the video.

1 year to the month, my Tekonsha controller has been flawless. got into a much heavier crosswind once that the Suburban could handle, and reached down to the controller and hit the Trailer Brakes..... worked like a charm, straightened us out immediately. I really like the variable power feature, I can change it depending on conditions as to how much trailer brake is needed for just creeping along..... my old controller was a "set it once" and that is it.... so the trailer always hit hard first. not this one, it is extremely good at sensing how much brake the trailer needs. 581279

  • Brake Controller Recommendation for 1999 Chevy Silverado
  • The correct brake controller harness for your 1999 Chevy Silverado is the part # 3025-P. Which for an economically priced brake controller that will still work great the best option is the Tekonsha Voyager part # 39510 as it is a proportional controller. Proportional means that it can sense the amount of braking your truck will be doing and will apply the same intensity to the trailer's brakes.

For a brake controller 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.

  • Installing a 7-way Trailer Connector for an Electric Brake Controller on a 2001 Chevrolet Silverado
  • The wires for a 7-way connector should be under the rear of your 2001 Chevrolet Silverado already. Use a circuit tester, like # 40376, and test the wires for their function. Then you can install a 7-way like # PK11898. Or if you wish to keep the 4-way and add a 7-way use # 37185. Then you can install an electric brake controller like the Prodigy P3 # 90195 using the wiring adapter # 3025-P.

You can use your test light to test the connector on the vehicle (where 3040-P plugs into) and see if it has power when you step on the brake pedal. If it does then check to see if the red wire is connected in the corresponding location in the harness. If not you can move it. If there is no power then there is something amiss on the vehicle side...

  • Installing a Brake Controller on a 2001 GMC Sierra 1500 with Factory 7-Way Trailer Connector
  • Since your 2001 GMC Sierra came with a factory installed 7-way trailer connector, GM should have already completed the connections under the hood at the fuse box. However, we have found that GM did not complete the wiring on all trucks, even if they came with the factory trailer wiring. If you plug in your brake controller using a plug-in style wiring harness, like part # 3025-P for Tekonsha brake controllers, and the brake controller does not power on, then the wiring under the hood...

  • Installing a Brake Controller on a 2000 Chevy Silverado
  • There are some connections under the hood that will need to be made to complete the installation of the Tekonsha P2 Brake Controller # 90885 with Wiring Harness, # 3025-P. Once you have plugged in the # 3025-P harness into the port to the left of the brake pedal, you can make the connections under the hood. Locate the power distribution box. There will be a bracket on the driver side near the windshield that will need to be removed. Remove the bracket and power distribution box cover....

  • Tekonsha Prodigy P3 Only Works with Manual Override on a 2002 Chevrolet Silverado 2500HD
  • It sounds like there is an issue with the stop light switch connection on the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 in your 2002 Chevrolet Silverado 2500HD. The most common problem that causes this connection issue is a blown Center High Mounted Stop Lamp (CHMSL) fuse which is in the engine bay fuse block. If you are using a hard wire harness then check your connection to the stop light switch wire attached to the cold side of the brake pedal or the one that only gets...

  • No Power on Brake Controller Red Wire
  • What is the year, make, and model of the vehicle? The red brake controller wire should only be getting power when you step on the brake pedal. If you are not getting any power on that wire with the brake pedal depressed then you may have it attached to the wrong brake switch wire (if it is hardwired into the vehicle), the red wire is in the wrong location in the plug (if it is a plug in application) or you have a blown stop light or CHMSL fuse. I would need to know the year, make, and...

  • Wiring Adapter Needed to Install Prodigy P2 90885 in 2000 Chevy 2500
  • Yes, the brake controller wiring adapter harness you need to install a Prodigy P2 # 90885 in your 2000 Silverado is part # 3025-P. The 2003 Chevy uses harness # 3015-P. These are pinned-out differently.

  • Recommended Brake Controller and Wiring Adapter for a 2001 Chevy Tahoe
  • If the trailer has electric brakes, you will need a brake controller to actuate them. GM didn't start offering a factory brake controller until a few years later. I would recommend the Tekonsha Prodigy P2, part # 90885. The Prodigy P2 is one of our best selling brake controllers, because it is very easy to operate. You will also need the Brake Controller Wiring Adapter, part # 3025-P that would allow the controller to plug into the port located in the junction box under the dash. We...

  • Need a 7-Way Trailer Connector for 2000 Chevrolet Silverado 1500 Without Factory 7-Way
  • Thank you for submitting a photo of your vehicle wiring. Your 2000 Chevrolet Silverado pickup should have a trailer wiring harness at the rear bumper. This harness is often tucked in behind the spare tire or zip-tied to other wiring or to the vehicle frame to keep it out of harms way until needed. Please note that in 2000 Chevrolet produced both C/K series and Silverado pickups. The harness may be terminated with a round plug that would fit into the back of the Pollak 7- and 4-way connector...

  • Recommended Electric Brake Controller for a 2000 GMC Sierra 2500 Towing a Tandem Axle Travel Trailer
  • The # 90885 Tekonsha P2 brake controller would actually be a great choice for your 2000 GMC Sierra. This unit is proportional, and works for up to 8 trailer brakes. You may have received a factory pigtail with your truck, usually stashed in the glove compartment. If so, you would only need the brake controller itself, as you would use this factory wiring, connected to the pigtail included with the P2, to plug the brake controller into your vehicle. The factory wiring might not match...

  • Parts Needed to Add Electric Brakes to Trailer with 3,500 Pound Axles
  • To answer your last question first the trailer has been towed with no brakes so even if you only add brakes to one axle it will be an improvement. Based on your measurements I'm thinking your inner bearings are # L68149 (1.378 inch diameter) and outer bearings are # L44649 (1.063 inch diameter). Very close to what you have but you'll want to double check like you mentioned. If these bearings are correct the hub and drum assembly for your trailer is # AKHD-545-35-K. If they're not...

  • Brake Controller Recommendations for a 2003 GMC Sierra
  • Yes, you will need a brake controller to operate your trailer brakes. For your 2003 GMC Sierra, our most popular brake controller is the Tekonsha Prodigy P2, part # 90885. You will also need the Brake Controller Wiring Adpater, part # 3015-P. One end of the Adapter plugs into the Prodigy, the other end plugs into the installation port located on the firewall behind the emergency brake pedal. For your convenience, I will provide a link to our GM Truck Brake Controller Install Guide. This...

  • Ease of Installation of a Weight Distribution System with Sway Control on a Jayco 22FB Trailer
  • Installing a weight distribution system with sway control, like the Reese Strait-Line Weight Distribution systems is not all that difficult. I actually feel that if you installed it yourself you would have a better working knowledge of the system and how to properly set it up and use it, because your trailer weight and the weight behind the rear axle in your tow vehicle may change over time and the system will need adjustment. The proper weight distribution system should be selected...

  • Trailer Brake Controller Wiring Harness for a 2003 Chevy Silverado
  • It sounds as if you might have the wrong wiring adapter. The wiring adapter for the 2002 and 2003 Silverado will fit either vehicle, but the order in which the pins are wired is different. Therefore if you have the incorrect one, it will still plug in, but will not work correctly. For the 2003, you would need part # 3015-P, not the 3025-P which is for the 2002. This can easily be verified by using a circuit tester like part # 40376 on the red wire exiting the rear of the controller....
