I obtained a shift **** from a GTP that has a performance mode button.
The transmission tables are there for performance mode.
How do you wire the button to activate the performance mode?
I assume it triggers from the PCM and there is not a different control on the transmission.
I was told that somebody sold a wiring "kit" at one point that added a pin to the PCM harness.
There is obviously part of the wiring harness where this attaches. Harness from a GTP work?
Anybody got any ideas?
Thanks
