Question:

I have a 14’ x 77” trailer frame with one axel with brakes. I have this part 7-Way Blade Trailer Wiring Harness - Molded Plug and the break away. I need a wiring harness from there back to brake lights, clearance lights. Do you have any? Thanks, Larry

Hey Larry, we actually sell jacketed 7-way wiring with the part # DW04914-1 by the foot. This would allow you to have all of the 7-way circuits to the back of the trailer like you are needed. You would just need to order a quantity of this that you need in overall feet. So for example, if you need 20 feet just order a quantity of 20.

Do you have a video to assist me with this project? Thanks, Larry

@LarryS We have videos for replacing 7-ways at the front of a trailer but we don't have anything oddly enough for from there to the rear of the trailer. Since every trailer is different though a video probably wouldn't be super helpful anyway.
