tach wires
hey, i got a tach in the mail today and the instructions on it were useless, these r probably the shittiest instructions ive ever seen for anything, anyways, theres 4 wires on the back, red black green and yellow, i know black is ground and green is the signal from the engine, however i just wanted to double check with someone with a little more experience on the red and yellow wires, im assuming red is 12 volt constant and yellow is 12 volt ignition, can someone please tell me if this is right or not?
