wiring an LSI IAC
I have a throttle body for my single plane conversion that uses an LS1 style IAC valve. It uses four pins as the TPI style IAC did, I am wanting to know how to wire it, what wire is what? Any ideas?

In 2000, it was:
Pin A, LT GRN/BLK, VALVE COIL B SIGNAL LOW
Pin B, LT GRN/WHT, VALVE COIL B SIGNAL HIGH
Pin C, LT BLU/BLK, VALVE COIL A SIGNAL LOW
Pin D, LT BLU/WHT, VALVE COIL A SIGNAL HIGH
1992 TPI colors are the same.
