    Connect the wire from the Alternator "L" terminal to C2 pin 15.

    If you are using the 1998 IPC (gauge cluster), connect the wire going to the "charge" or "battery" display lamp to C2 pin 35.

    If it is a newly manufactured wiring harness - then it should be OK - as long as it was wired (pinned) for a Camaro APP (pedal).

    PE delay parameters - time, temp, and RPM - are available in the 1999 and 2000 OS. It is the ramp in / out rate (i.e. rate of EQR change) that was not available until 2001.
