Hi, I have an old school RAZO dual stage shift light, and have hooked up the tach sense wire to pin 7 (yellow with red trace) on a R32 GTST and it is not seeing the correct signal.
I also hooked up behind the tacho with the same result.
The factory tacho works perfect, and I have tested this in my other car, a SVO Fairmont Ghia which has the same shift light, and the modules are both working correctly.
When I looked at the instructions that came with it, it is stating to pick up pin 41 (Green with black trace) Crank Position sensor (120')
Before I do this, I just wanted to see if anyone has come across this before?
I did some searching in the forums, but came blank with hooking up to pin 41...
