Re: tac wiring question

3 or 4 wire depending on your tachometer.

Probably a White/Red/Black/Green setup, on a lot of aftermarket tachs, the 4th being white, for a lighted tach, if applicable.

Red -Switched 12v from panel/block/wherever.
Black - Ground
Green - Dist-Hei-Coil hook up. (Labled 'Tach' on most Hei's, not sure about a coil)
White- Lights, splice in junction with dash lighting past the dimmer

Not sure if you have a general aftermarket tach, someplace there's settings for 4,6,8 cyl that has to be adjusted.
