Installing a tach

[GTman85]

Trying to get my 5" tach hooked up in the Z but am having some difficulty with the wires:mad: Can someone give me an idea which wires are which. Red=hot, White=lights. Now the prob is finding out where the green and black should go. Any info would be greatly apprec.

I think Green is coil and black is ground.... I think I'm right...

[joebobclark]

Black is ground = ground to some point on chassis

Green is Signal = Tach signal should be a White/Black wire on the Coil/Distibutor..... I am pretty sure

Thanks
Chris
