Thank you for your detailed information Jorb. That explains why when I got the truck it had no dome light. I bought a repop dome light a while ago and tried to run the wire through the headliner but was never able to fish it through successfully. If you know of a good way to get a wire for the dome light to the switch bypassing the headliner let me know??

So after I wrote my question on here, I found out after searching the internet that the orange wire was the stop light wire. I repaired the orange wire and my brake lights work again. So like you said, the switch must have shorted out. It looked to be original to the truck as I actually had to drill out the retaining nut to get it out. I ordered a couple of connector housing to replace the ones that were damaged. Happy to report that the NOS switch i installed is working and all my lights are too.

Thanks!!
