Question:

Do you have a wiring diagram for 7 way class c that goes to my 6 way 2016 subaru. After an accident the wiring pulled out of the 7 way connector going from the tow vehicle to the RV. The diagram on the website doesnt help. Its a 7 to a 7. I also have a brake assist.

If you are needing to wire the 7-way end of your adapter connection the attached wiring diagram can help with the wire locations.

The wiring for the 7-way will be this:

1 o'clock position - Black wire auxiliary power
3 o'clock - Brown Right Turn & Brake
5 o'clock - Blue Electric Brake (if applicable)
7 o'clock - White Ground
9 o'clock - Red Left turn & Stop
11 o'clock - Yellow Taillights
Center - Reverse Lights (may not be used)

Using a circuit tester, like # PTW2993, can help you locate the correct RV wire function when trying to match to your harness adapter.
