Hey Guys, Ive just recently purchased a Auto Meter Tacho with Shift LIght and ive got most of the wires working. Red being for ignition, white for the lights, black being earth and my final wire to join with some other wire which is my question. Where do i find the existing tacho wires so i can hook up my new tacho. Btw i have a 89 integra sx 1.6L any help will be appreciated
