Well, was doing some shop cleanup today and found a light bar up on a shelf long-forgotten about. Think it came off an old ford ranger of mine. Anywho, decided why not put it on the Yukon tonight. Added a relay beside the underhood storage box, the relay uses one of the AUX terminals in fuse box to grab power, the high beam switch activates the relay. So, light bar comes on with the high beams. Saves a lot of time not having to run wire into cab and drilling a hole to add a switch somewhere. Should make my night drives through the woods a bit brighter.
