Corvette C6 Window Switch
2005 Corvette LS2: Tach wire located at PCM (behind passenger side wheel well), blue connector (C1), pin #48, white wire. This wire also runs to the instrument cluster (pin#5/connector #2) and to the Heads Up Display module (pin#4).
2006 Corvette LS7: Tach wire located at PCM (behind passenger side wheel well), black connector (C1), pin #48, white wire.
**NOTE**
For LS1/LS6/LS2/LS7 engines, set shift light to "4 cylinder" mode for 2 pulse/rev (PCM tach out terminal is "2 pulse/rev)
Best place to get tach is on the passenger side coil packs off the main connector. It should be a green wire. The wire will be either solid green or green with a white tracer.
Mine was green with white dash setting 1 on Nitrous outlet WOT/WS
Its in the middle you can disconect it to make the connection.
TPS comes right off the side of the TB connection on pass side the green wire, I tapped into it a few inches back so the connection is under the fuel rail cover.
Have not tested that on yet, but the setup worked.
