question about painless harness to a 71 240z 4 wire tach... I'm confused about how to hook this up- I have a purple wire coming from the coil and a red white power wire to supply power to the guages- the tach has a loop of wire white with black and white with red (same wire loops through a coil) a yellow/ red and a black... assuming black is ground, how do I hook this up? I called painless today and they were like uh...get a chevy dude... any help appreciated. thanks for this thread!
