was looking around and found a two wire connection that I am not sure if it is hot or keyed power , tucked behind the bar on the gas tank. LS sells a switched light that plugs right into this but is $99.
I have separate switches for headlights, hazard lights and the grill work lights. Mine is a XR 3037.
In response to your query, I had the headlight switch in off position and the individual wires to the headlights disconnected. I then pressed the grill work lights switch to "on" position and the fuse for the work lights blew out immediately.
