Auto dim/E-compass mirror
I dont want an OHC, I have more storage than I need right now. So I figure I could get something like a Gentex mirror or something off ebay or a GM junker and wire it in. My question is, would I be able to wire it into the Dome light in the truck? Since it can draw its own power or would I need to put it to something thats on constantly like the PCM power wire?
