12V+ Coil wire

[sawman70]

Does anyone know the pin # to hook up a tach sending unit on a 2003 Cobra. Want to hook it up and save a little time.

Thanks much

Pin #26 on the ECU harness (it's light green with white trace)

Thanks.

It is pin #34 on the 42 pin harness, passenger side firewall. Red with green.

Hooked it up today.

That's one of the other coils I believe...but it should work out the same...

All coils use the same 12V +. It is the 12V- which controls the spark.

Looking back, I beleive it was the same pin on my 99 GT I used.

Either way. Tach works great.

Gotta love the big tach, never hit the rev limiter again.
