Alternator help

I have a 94 s10 with a lq9 swap. I swapped all the accessories over to c5 corvette. The c5 corvette uses a valeo alternator that runs through the pcm when using a factory harness. I am running the holley hp and I am not using a factory harness so I planned to convert the valeo style alternator over to a 1 wire. From what I just learned they don't make a 1 wire regulator for the valeo alternator.. any suggestions please? Thanks in advance!

Search here for carbed LS swaps. No ecu and alternator is set up like a 1 wire.

Maybe look for a pic I posted of my alternator wiring setup. I'd do it, bur my phone isn't playing nice today.

All you need is a switched power source to the second pin as viewing the alternator from the rear. The line needs to be run through the dummy light circuit in the dash or have a resistor installed. Google around for the exact value.
