Rich_Rolla Posted August 10, 2008 Report Posted August 10, 2008 (edited) Just wondering about getting a tacho in my car. I drive a 87 hatch. I've heard from a few people that a similar model dash will plug straight in and the tacho wires are already there. I'm wondering, if I bought a custom tacho from somewhere, would it plug straight into the existing tacho set up? If not, what would I need to wire it to, to get it to work? Cheers, Tim.

JayJay Posted August 10, 2008 Report Posted August 10, 2008 Nearly all after market tachos have the same wiring Positve Earth Lights Memory and signal. You can get a signal by connecting the wire to the negative side of your ignition coil. JayJay Quote
