Parts Needed to Add a Trailer Brake Controller on a 2000 Toyota 4Runner
Question:
I read the article on which wires go where on the C57102 but I have a 2000 4Runner with factory tow package. I want to add a brake controller to use with a new trailer using the 7-prong connector. I know I just plug the 4-pin plug into my existing 4-pin socket but do I connect the other wires to the brake controller and/or directly to a wire located where? The 4Runner already has the taillight converter so I dont connect there. I found out 2003 is the first year the brake circuitry was run to the back. If you have time, Id appreciate a suggested list of parts to add a brake controller with the C57102 to a 2000 4Runner SR5 with factory tow package. Any manuals would be great. Thanks.

The information I have on a 2000 Toyota 4Runner is that a brake controller has to be hardwired in so you would follow the instructions in the FAQ I have linked.
The black wire on # C57102 will connect to the positive battery terminal via a 40 amp circuit breaker # PK54540. The white wire will ground to the vehicle frame. The yellow wire will connect to the reverse light circuit if the trailer has reverse lights. The blue wire will connect to the blue wire from a brake controller.
For hardwire situations we normally recommend the # ETBC7 which comes with everything needed to install a 7-Way and wire in a brake controller. But for # C57102, you will need to add the circuit breaker listed above, about 25 feet of wire # 10-2-1, and either a 20 amp circuit breaker for 2 to 4 trailer brakes # PK54520 OR a 30 amp breaker # PK54530 for 6 to 8 trailer brakes.
Then to wire in the brake controller remain wires, the white will ground to the negative battery terminal, the black will connect to the positive battery terminal via the 20- or 30-amp circuit breaker, and the red wire will attach to the cold side of the brake switch.
You will need a circuit tester like # PTW2993 if you do not have one already. Test the wires on the brake switch located above the brake pedal until you find the one that only carries a brake signal when the brake pedal is pressed. If they same wire has a signal with the running lights or turn signals on it is not the correct wire. I have included a video that should also help.
For a brake controller, I recommend the Tekonsha P2, # 90885. It is one of our bet selling controllers because it is easy to set up and easy to use. I have linked the instructions for you to view.
