Since I only have one light bar, the Vision-X Xmitter Xtreme 21" in the lower grill here's how I chose to wire it. I used both Upfitter 1 and Upfitter 2 switches to power the one bar. I used a relay in the Upfitter 1 circuit that the coil is operated by the high beam headlight wires. Anytime I hit the high beams the relay coil is energized and if Upfitter 1 is turned on the light bar goes on and off with my high beams. Upfitter 2 is wired directly to the light bar so that anytime I hit it the light bar comes on whether the headlights are on or off.
