I tried that way originally and due to the headlight wires all having 12.6 volts on them with the lights off, the grounding wire at 86 that you mentioned will keep the light bar on when the truck or the lights are turned off.
Again, I am not 100% sure that I am still fighting a DRL issue as well, which may be giving me a bunch of false results.

So it's wired like I said before with the only difference being that the ground is the ground on the headlight plug.

If you're going to run the 100/80 watt bulbs like I am then you'll want to think about getting the LMC headlight harness because the higher wattage bulbs along with whatever the light bar is pulling will cook a headlight switch pretty quick.

FYI - The higher wattage bulbs are worth it. They're labeled as offroad bulbs by Hella but they don't blind people like all the people running LED lights in stock housings so I don't pay any attention to the off road only rating. My 2015 Mustang with HID lights aren't as bright as the lights on my truck.
