For some reason I never got the tach output working with my old build. Thought I'd get that sorted now the car is back up.
So I remember it being different than the NAs, but I can't remember how, so can anyone point me to the right thread? I tried searching around for the past bit and can't find anything.
Thanks

The dashboard tach on an NB is fed by the ECU, similar to a '95.5 or later NA.
On an '00, it's a green / orange wire at position 2K of the ECU. Set up a circuit in the MS to give it a 0-12v squarewave with one pulse per ignition event.

Dang, duh.
Thanks, I'll get in there tonight and get that gauge finally working. You know I just lived with it for 6 months before the car went down that I didn't work...
Appreciate it guys.
