Tekonsha Accessories and Parts - 3021-S

  • Trailer Brake Controller
  • Wiring Adapter
  • Wired to Brake Controller
  • Tekonsha
  • Vehicle Specific

Streamline the installation of your trailer brake controller with this custom adapter. Simply connect the wires of the harness to your brake controller and then plug the other end into the built-in port beneath your vehicle's dash.


Features:

  • Pigtail wiring adapter eases installation of your electric trailer brake controller
  • Connector end plugs into the built-in port beneath the dash of your vehicle
  • Wire end connects to the wires on your brake controller with butt connectors (sold separately)
    • Compatible with time-delayed and proportional brake controllers from TrailerMate, Draw-Tite, and Tekonsha
  • Limited 1-year warranty


Installation of Tekonsha Brake Controller Adapter

To install your electric brake controller, you need to connect the wiring of the controller to your vehicle. Certain auto manufacturers offer pre-wired options, typically known as tow packages, wherein wiring is run for you from the dash to the trailer connector on the back of your vehicle. When this is done, a port is installed at your dash so that you can easily plug in a brake controller.


This adapter plugs into the 4-pin connector on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal.


To hook this adapter up to your trailer brake controller, just connect the 4 wires of the harness - ground, power, brake switch, and brake power - to the corresponding wires on the brake controller. If your brake controller came with a plug built into its wiring harness, you will have to cut off the plug and connect to the wires themselves.

The staff at etrailer.com are very helpful....they don't finish with you until they've answered all your questions and have provided the proper equipment to do the job. Rush shipping got the brake controller here next day, just in time for my long trip hauling a trailer.

2012 Dodge Ram Pickup

Super easy plug-n-play on my 2012 Ram 1500 with factory-installed towing package. This plugs right in beneath the steering column, then you just connect it to your choice of brake controller. Couldn't be easier.

etrailer has the BEST customer service on the web too!

One year after installation, my Prodigy P2 still works flawlessly. It was easy to install after reviewing several of the resources on etrailer. I am very satisfied with the purchase. i have been considering purchasing another harness adapter so i can move the unit back and forth from my pickup to my RV.

was difficult to find a good mounting location away from leg room

Perfect fit. Looks to be of high quality. Would recommend.

Quick/Easy Brake control installation using this connector. I actually swapped the black and blue wires to use it on my 2014 Cherokee, and it works great. Excellent product, super fast delivery, and well worth the price to 'do it right'.

Item worked good. Wired up correctly and plugged into the factory harness. No guess work. Blue wire to blue, red to red, white to white, and black to black.



by:

This is excellent. It plugged right into the port on my truck and thankfully i have the factory tow package. It made installation of my brake control very simple. Highly recommend it

  • Location of Brake Controller Connector on 2012 Ram Truck
    The connector you are looking for will be located taped to another larger wiring harness just to the right and above the emergency brake pedal, as shown in the photo I have edited for you. You can confirm that this is the correct connector by testing it with a circuit tester like part # PTW2993. One pin should show a constant 12-volt power supply, another should show voltage only when the brake pedal is pressed. Unfortunately, my contact at Tekonsha was not able to shed any light on...

Next, touch the red lead to the top left terminal, this should show 12 volt power when the brake pedal is pressed. The bottom left terminal...

  • Location of Brake Controller Connector on 2010 Dodge Ram
    The brake controller installation on a 2010 Dodge Ram would be pretty much identical to that as the 2009 model shown in the video. The installation port is located under the dash midway between the emergency brake and the brake pedal, just above where your left knee would be as you are sitting behind the wheel. The connector is either white or light blue in color. If you need the wiring adapter that connects the brake controller to the under-dash connector, we offer it. The part # is 3021-P...

  • Hardwiring a Reese Brake Controller to Factory Brake Control Harness on a 2011 Dodge Ram Sport
    On your 2011 Dodge Ram Sport the wire colors you have do not match anything that I have on the factory brake controller harness so to determine the functions the factory harness will have to be tested using a circuit tester such as # 40376. There should be a wire that has power all the time. This is the 12 volt wire and connects to the brake controller black wire. There should also be a wire that only has power when you step on the brake pedal. That wire will connect to the brake controller...

  • Parts Needed to Install a Hopkins Trailer Brake Controller on a 2012 Dodge Ram
    Since you have a connector on your 2012 Ram 1500 and a Hopkins brake controller, you can just use the plug and play harness # 3021-S. Otherwise, you would need to use a circuit tester like # PTW2993 if needed and test the wires on the connector you found for function. The 12-volt power and brake light wire will be easy to find but the ground and the brake output will not because they will not have power to test. On the truck find the 12-volt power pin. Hold the plug so that the 12-volt...

  • Parts Needed To Convert A 2021 Crossroads RV Redwood 3951MB To Disc Brakes
    Hi Floyd, Before we can confirm the correct kit will also need to figure out what bearings/grease seal match your spindles. You can remove them from the current hub and see if the part numbers are still stamped into them or you can measure the spindle at points B, C, and D on the diagram below with a set of calipers # PTW80157. From there you'll want to take a tape measure and measure the distance from where the actuator is going to sit back to the first axle, keeping in mind the distance...

  • Hopkins Brake Controller Plug In Wiring Harness for a 2012 Dodge Ram 1500
    I checked with Hopkins and brake controller wiring harness # HM53015 does fit a 2012 Dodge Ram 1500 if it is equipped with a factory 4-Way or 7-Way trailer connector at the back. If you have a Hopkins brake controller that requires a plug in harness then this is the correct one for you. If you have a Hopkins brake controller that requires a hardwire from the controller to the harness use # 3021-S.

  • Troubleshooting Electric Over Hydraulic Trailer Brakes Delay with Dodge Ram OEM Brake Controller
    The OEM controller on your Dodge Ram truck should be proportional which means it will be applying your trailer brakes at the same time and with the same intensity that you apply the brake pedal in your truck. If you haven't gone through the truck settings and fine-tuned how it's setup then that can definitely be a contributing factor. You'll want to put it in the Electric Over Hydraulic setting for it to work properly. If changing it to this setting still doesn't fix things then it could...
