I just got some indiglo type gauges off ebay and they came w/all the parts but no instructions. I know in mod's there's pictures of the wire to use or whatever but none of this makes much sense to me. How do i get into the dash, where do i run the wires, what do i ground it to, what wires do i cut, and what else should i know? Please help me if you've done this before, i don't want to screw anything up. Thanks alot, Jamie
