So I've never done one, installing it more to keep an eye on boost, make sure I'm at proper, not too high not too low. Have the mounting cup, gauge, line, and T-fitting. Going to run it off the throttle body vacuum line. Now there are wires with crimp fittings at the end for I would assume lights? I'm not even going to attach them if they are for lights, as I don't really care all too much, and the less electrical work I have to do the better. Its an autometer 4303 gauge. Anything else I should look out for before I throw it in? Right now it seems fairly basic.
