um ok i dont have a tach. and i thought you could slip them over the needles which makes me happy. but theres a strip of something that came with the guages off this black box and it has sticky stuff on the back. whats that and where does it go? also where am i sposed to wire this thing to get it to light up? im not good at all with electrical stuff. and im guessing it plugs in there somewhere? im so confused i could puke well at least i know how to take the dash apart now. im gonna try to tackle this in the morning. thank you for the help
