I was going to build my own harness as I'm a wiring snob, but i was on a deadline and procuring the materials needed would've dragged the timeline out too long for my King of the Hammers trip. I looked at a few shops offering pre-built harnesses and decided on the CJC one for a few reasons. Namely, it broke the LP6 lights into a set of 3 and 2 to ensure proper circuit loading on my SPOD. Also, there are no relays in the harness so it's ideal to run with your switch system with integrated circuit breakers/relays to avoid doubling up relays and trigger wires. My SPOD allows me to run these on two circuits that i can combine into one button. The wiring it perfect; wires are quality 12awg for proper amp load, sheathing is tight and cut super clean, heat shrink is thick and includes adhesive, and even the length was perfect. I run magnetic zip-tie holders under my light bar and it has the perfect slack for an ultra clean look with my light spacing. I couldn't have built a better harness, myself. Great product!
