hey all, I just got a compass mirror (the standard one w/ out the dim feature) to replace the basic mirror in my RTS and I was wondering if anyone has a compass mirror installed in their RTS? The mirror came alone with no wire harness... Does anyone know if the dealer sells these wire harnesses alone? I think someone on here told me that the wire harness should already be in the top counsol or something. I was wondering if i should atempt to install it my self or if i should have the dealership do it for me? I know nothing about installing and have never worked on something like this before. Any tips or help whould be great on installing this compass mirror.. thank you!!
