prior to buying the vehicle the previous owner installed a UHaul hitch. went to rent a trailer and naturally their was no juice at the plug in. i took it to the shop i service my vehicle and they told me it was typical for Uhaul to install and not properly wire the lights. they will only replace with a LR wiring kit, cost is $350. so do i bite and let them do it or is their an alternate solution....? certainly hate to spend that kind of money to fix something that was never installed properly in the first place. thanks
