Mk2 tach input/power pins by blackdogvan on 16 Dec, 2010 20:33

Can anyone tell me why some diesel tachs from the 80's qauntum / vanagon / jetta era have 3 input pins & others have 4?

Figured it out, one lead in the foil circuit "board" does a loop. So all the tach's i've been playing with (gas / Diesel) share the same 4 pin, 3 socket on foil connection. Whew, I bet there was quite a few sleepless nights out there in vwdiesel land over this...
