I own a 1996 base model eclipse, which comes stock from the factory with out a tachometer gauge. I purchased a tachometer and the problem I'm currently having is finding the tachometer signal wire, i have been told it is still there and i need to splice into it, I'm sure there should be one from the ecu and behind the gauge cluster I just can't find out which one. The other question was which wire is the positive ignition switch wire?
