I'm trying to set up the interior of my cab very simple and minimal, my truck came stock with the factory dome and cargo lamp however they had been ripped out by the PO before I got the truck. I'm currently in the midst of trying to reassemble the domelight inside as well as the cargo lamp on the rear of the cab, I have both the dome light and cargo light housings and a factory cargo light switch, however none of the wiring exists. The PO hacked everything up. The door jamb switches for the domelight are shot and again the PO ripped out the wires to the switches anyways . However when the headlight switch is turned all the way right or left the interior courtesy light illuminates so I know that curcuit is still good. So basically my questions is, is there any way I could do away with the door switches and just operate the ctsy lamp and dome lamp off the headlight switch after I install it? If so where would I run the wiring for the dome lamp to tie into that curcuit? Also where would I get power for the cargo lamp? I'm not to familiar with that curcuit. Any help or suggestions is always appreciated thanks fellas!
