I don't really care about the price to get one installed. I got the truck for too good of a price to complain about spending a few hundred on the trailer harness.
What would I need to run for wires? I assume the battery wire to the rear for 12V supply and one to the inside for the brake controller. Are the wires pre-run from the factory to the back for the brake controller, or do I have to replace the whole trailer harness to get the 7 blade hook-up? |
