I have a TBI engine in a 1992 GMC Safari, I want to hook up my aftermarket tachometer but I have no idea what goes where red = +
Black = Ground, Green is probably lights and white must hook to something in the ignition but what?

Green is ground all around.

DJ, if you google the manufacturer of your tach, I'm sure there will be a website that will have the color code of the tach wires on it. That's how I found out which wire was which on the Sun Super II tach I had laying around .

Most tachs are
Black=ground
Green=lights
White= dist feed
red= power from ignition
There should be a white coming out of dist or coil, I believe you jump one of those to feed tach, but check with someone else here!!!!
