Looking For A Wiring Harness To Re-wire A Utility Trailer

Question:
Hi, we are looking to rewire a 15-year-old flatbed utility trailer that is 7 ft wide and 12 ft long with all new lights. Were looking for a wiring harness to do that job. I am not sure what harness to purchase. Thanks

Hey Jason,
I recommend the # TS67RR harness to re-wire that trailer. What I like most about this harness besides having length to do the full trailer, it is a wishbone style. That means is allows you to split the harness down both sides without having to jump wires across the trailer to the other side lights. It makes the installation a lot easier, and gives you that 4 flat at the front you need.
What are you towing the trailer with?

Hey Jason, how did things go with the TowSmart wiring harness on your flatbed trailer? Did the wishbone design make the rewire easier? Your update could make it easier for the next person working on an older trailer.
