I went ahead and had Uhaul wire because it was only like $10, so why not? They did hook into the tail lights, but only for the lights, they actually used a T connector into the factory harness. They did not however hook up the pins for the battery charge, trailer running lights, brakes, and trailer back up lights. I was stunned to find a slot in the power box for all the fuses myself since it did not have a towing package. My mailn question I guess is this, does anyone know if they is power wires back there from the fuses, or should I just pull wire from the battery and forget about the fuse panel? Thanks.
Edit... I tow a 19' Citation boat, an equipment trailer for work and I am soon to buy a new camper.
