Wire length between the two connectors is short for a full-size pickup
Size: 16AWG Wiring Harness-2 Leads
I used the harness to wire ditch lights on opposite sides of a full-size pickup (F150). The wire between the 2 2-pin connectors was about 18 inches too short. Fortunately, splicing the wires from the (Nilight) ditch lights and the included pigtails gave barely enough length to reach the connectors. The connectors are buried inside the trim channel for the cowl; I'd have preferred they were exposed on each side to allow for easy swapping of the lights, but I can live with it. There is more than enough wire from the first connector to the relay for my all-under-hood installation, but I didn't think to measure if it would reach into the truck bed. The harness is of good quality and is a very good value. It would be a 5-star if it weren't for that little length issue.

great value
Size: 16AWG Wiring Harness-2 Leads
very affordable light install kit. worth the price just in the wiring connectors. I used this with my Nilight front bumper kit. i bypassed the button and wired high beam (+) to the yellow small wire. I did this so when the highbeams come on the light bar comes on. because with the stock arragement of this harness, the button continously draws power for the indicator LED
