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.

  • 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....

  • 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 the...

  • 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...

  • Guide for Adding Brakes to Trailer and Brake Controller for 2000 Chevy Silverado
    I attached a link on this page that covers everything on adding brakes to a trailer like yours for you to check out. The first thing you'll need to know though is the axle capacity of your trailer and then the wheel bolt pattern of the trailer wheels as that allows us to pick out the correct hub drums and then build everything else needed based around that. If you can get me that info I can help more or you can try following the help article. Now for the brake controller I would recommend...

  • Brake Controller Install Harness Recommendation for 2001 GMC 2500HD
    The correct brake controller install harness for installing the Prodigy P2 part # 90195 in your 2001 GMC Sierra 2500 is the part # 3025-P. This plugs right into the junction box under the dash of your truck. In the attached install video you'll see how this is done on a very similar 2002 Chevy Silverado. If there's a connector already in the port you can simply unplug it and plug the # 3025-P in it's place.

  • Recommended Electric Brake Controller And Wiring Harness For 2001 Chevy Suburban
    For your 2001 Chevy Suburban, I recommend the Tekonsha Prodigy P3 # 90195. This brake controller is a proportional brake controller which means the same pressure and timing in which you hit the brakes in your Suburban is the same amount of pressure at the same time that will be applied to your trailer brakes. This brake controller has an easy to read LCD display that takes code deciphering out of the equation. It runs constant diagnostics and gives you a very easy to understand real-time...

  • 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 to...

  • Troubleshooting Trailer Brake Wiring Issues on a 2002 Chevy Silverado
    Thank you for being very detailed with your question! The first step I would take is to make sure everything on the truck and trailer is wired properly. Your Prodigy brake controller should have the wiring adapter # 3025-P which is custom for your 2002 Chevy Silverado. I recommend verifying you have the correct adapter because # 3015-P will also fit but it was pinned differently for the 2003-2006 Chevy Silverado's. The next thing I would check is the wiring for the 7-way connector at...

  • Parts Needed to Install the Prodigy P3 Brake Controller on a 2002 Chevy Silverado K3500
    To install the Tekonsha Prodigy P3 # 90195 on your 2002 Chevy Silverado K3500 you need the Wiring Adapter # 3025-P which plugs in under your driver-side dash (see attached install video). If you already have the factory plug at the back then you're good to start towing, otherwise you need to check above your spare tire for the OEM wiring. If you find a bundle of wires you'll need the Pollak Kit # PK11898, but if you find a connector instead then you just need the Hopkins # 30955 and you'll...

  • How to Disable OEM Brake Controller When Installing Aftermarket Controller
    You can easily install an aftermarket controller in your 2013 Chevrolet Silverado 3500 that is compatible with your trailer's electric-over-hydraulic (EOH) brakes. The linked article illustrates the process of wiring in a EOH-compatible controller like the Prodigy P3 # 90195. If you follow these instructions you will disable the OEM controller and this change will not generate any trailer brake display messages on the driver information center. The article includes photos and a wiring guide. You...

  • 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...

  • Should Red Wire for Primus IQ Brake Controller Always be Hot
    You definitely did find the culprit! The red wire should only get hot when your brake pedal is pressed. This tells the Primus IQ # TK90160 that you are stepping on the pedal so that the controller, in turn, will activate the brakes on your trailer. Check for any places where that wire is damaged and try to repair it as that would be the problem. If you can't find any places where it looks damaged then you may need to use something like the Pacer Performance 3rd Brake Light Logic Module...

  • How Does Auto-Leveling Capability Simplify Installation of a Trailer Brake Controller
    The Tekonsha Voyager Proportional Trailer Brake Controller # 39510 will install in a 2002 GMC Sierra (if it is equipped with a factory 7-way) using quick-connect wiring adapter # 3025-P, which plugs in under the dash as shown in the linked video at the 4:54 mark. A brake controller that offers automatic leveling, such as the Prodigy P3 # 90195, does not require that the mounting position be exactly straight in order for it to operate properly. The Voyager does require that it is mounted...

  • Brake Controller Installation on a 1999 Chevy C3500 Pickup Truck
    On a 1999 Chevy C3500 there will NOT be a brake controller port to plug in a brake controller. The brake controller has to be hardwired into the truck. Chevy did not start putting in a port until they switched the trucks from C or K to Silverado. Prior to that Silverado was just a trim option. I have included a link to a video that will help. It shows installation on a 1996 C/K series truck. Installation will be basically identical on your 1999 model. If your truck already has a 7-Way...

  • Where Is Brake Controller Install Harness for 2001 Chevy Silverado 3500
    While it looks like you are pretty close to finding the correct port for installing a brake controller in your 2001 Chevy Silverado I attached a picture of where the install harness does plug in using a harness like the part # 3025-P. 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. This is a proportional brake controller that senses the amount of braking...

  • Are Additional Fuses Required for Installation of Tekonsha Prodigy P3 on 2002 Chevy Avalanche
    Installation of the Tekonsha Prodigy P3 Trailer Brake Controller # 90195 should not require any additional fuses or wiring connections. You can plug it into the port under your dash using the # 3025-P and it will be ready to go. However, I did find some instances where the fuse was missing. If that is the case, it looks like you need a 40 amp fuse for the brake controller and it appears to be in the engine compartment fuse box. I recommend consulting your owners manual for the location...

  • 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 2002 Chevrolet Silverado
    If you have a 7-way connector at the rear of your 2002 Chevrolet Silverado 1500HD, the installation for a brake controller can be very simple. If you have a brake controller, you will need to know what the manufacturer is and you will want to see if there is an adapter that can plug into the harness on your Silverado. If you do not have a brake controller I recommend part # 90885, and then an adapter that will work with the brake controller. I recommend this brake controller because...

  • Wiring a 2003 Chevrolet Kodiak C-5500 for a Brake Controller with Factory Style Wiring Harness
    When wiring the red brake switch wire on the brake controller you should use a circuit tester to determine the wire that goes hot only when the brake pedal is pressed. If you find a wire that has voltage on it before the brake pedal is pressed and then gets brighter when the brake pedal is pressed that is the wrong circuit and should not be used. If your Kodiak has the prewired connector under the dash for the Tekonsha Wire Replacement for GM Vehicles, 2003 - 2006, then this should be...

  • Trailer Brakes Do Not Work on a 2003 GMC 2500 With a Factory Tow Package
    To start off you need to check under the hood to make sure the wiring connection mentioned in the GM brake controller FAQ article attached are made. In the 2002 - 2003 model years, GMC changed the way you hook up the brake controller under the dash. There are two possible wiring adapters that will fit the connector under the dash. The 3015-P and the 3025-P. The only difference between the two is the way the RED wire is pinned out. The red wire carries the signal from the stop light switch,...

    On your 2002 Chevy Silverado 2500 HD, you will need to look above the spare tire for a round plug with a cap on it. I have included a picture below that shows what the plug looks like. If your truck has this plug, then it has the wiring for a 7-Way. To add a 7-Way trailer connector at the rear of the truck, you can use Pollak Replacement 7-Pole, RV-Style Trailer Connector Socket - Vehicle End, # PK11893. The factory harness from under the spare tire will plug into the back of this connector....

This has a max towing capacity of 12,000lbs and max tongue weight of 1,200lbs; or 14,000lbs and 1,400lbs when used in combination with a weight distribution system. This hitch offers a simple bolt-in installation, requiring no welding or drilling. Your Silverado may have come with a factory 7-way trailer connector that was converted to...
