Awesome man. Thanks a ton. I have a harness that runs up my pillar with several wires but then it branches off into only 2 for the dome light. Would I be able to tap into all those. Could you tell me what each wire is if I post the colors?

 

These are my judgements on colors. I think that's all of them. If none of these are for the bus could you tell me where I could find a wire for that? Thanks again
