This is a great solution for bringing the upfitter wiring topside, especially if my 2022 Ford diesel with little clearance. Customer Service is excellent, very quick response, product well made. Love it.

Totally impressed with the harness made of premium material built and designed to be functional right out of the box. Built like no engineer would build it so it works!!

True Innovation with Quality Workmanship

If you are like me, looking for ways to extend the short Ford up-fitter wires from the bottom of the relay box, then look no farther than Open Trails Creations. I opted for what ended up being the brand new 10 wire (6+4) harness. The attention to detail with the connectors to the 3d printed caps, is second to none. Between the workmanship, the impeccable details to shipping, to fantastic chat conversations, you won't be disappointed!
