Question:
Hi, I want to tow my 2012 chev silverado 1500 4wd behind my motorhome. I already have all the hardware installed on my truck to hookup the tow bar, but I need all the wiring harness items to hook up the lights. My motorhome has the towing 7 way harness plug. Can you guide me to the right items I need to purchase?
