LS Swapped squarebody

[Wide Open]

I found this -

The CPP has both a normally open circuit and a normally closed circuit in it. The normally closes circuit send 12v to the ECM at all times. As soon as you start to push the clutch, the normally closed ciruit opens removing the 12v from the ECM and disabling the cruise control. When the clutch is pressed all the way down, the normally open circuit is closed sending 12v to another pin on the ecm which will allow the vehicle to start.

Pin A PPL wire is for the TCC brake switch/cruise control release signal
Pin B brn/wht CPP switch signal
pin C lt grn igntion positive voltage
pin d ppl/wht starter relay coil supply voltage
pin e brn ignition 3 voltage
pin f gry CPP switch signal
