I haven't the faintest clue about wiring - but here's what I was thinking to run lights from the roof: There's a stock wire coming out to the driver's side bed rail, which used to connect to the bed roof, I suppose to power the tailgate window. There's a connector on the end of it and there's actually two wires inside. One of these is live and I found I can plug a light wire straight into it and the light works. The other when grounded turns on the cab light. OK, here's the thought. Can I just use this live wire to power my roof lights? Basically, I'll just connect a new wire to the stock one, run it through a switch and then up to the lights. I need simple on-off for all four roof lights, no need to run them independently or in pairs or anything. I believe the stock wire should already be fused. Would this simple set-up work?
