Finishing up the rewire on my 75 k5 using ez wiring kit. I'm at the dome and interior lights. It has a hot wire going to the dome light but not sure how to bring the ground to it. I have the previous wiring it wasn't hooked up right. It has the 2 door jam switches that go to a light socket under the dash. The socket has 3 white wires and an orange wire. Also there is a wire coming off the head light switch that my instructions say is dome light return. Any help or diagrams would be appreciated.
