Delco is 4 wire ISCV, works the same as Toyota's 6 wires ISCV's (but without the 2 power wires).
I know for a fact the LT8S and LT12S (and its predecessors) cannot control this.
If he has an LT10S, then it has an extra 2 PWM wires. Whether these can be reconfigured to work with the other 2 PWM wires, I don't know.
Its a call to Microtech for j00.
