In case anyone else is interested, I got in touch with Power Commander and this is the responce I got:
====================================================
I am not sure what type of signal your shift light is looking for, but if it is looking for a ground pulse corresponding to RPM, you can get that from one of the output wires of the PCV.
You are not going to find that signal on any of the module's wire inputs like the Quickshifter connections.
The output wires of the PCV are the white wires with a tracer color corresponding to the solid colored input wires.
Let me know if you have any further questions.
====================================================
I'm not sure exactly what he means as there is no white wires on the PCV. Does anyone know what he might mean??
Cheers,
Boogs...
