So I bought & installed the Ron Davis 3rd gen radiator upgrade with the dual fans etc.

Strictly following the directions it works as expected.

2 problems at the moment...

1. IF I leave the factory temperature gauge hooked up to the coolant temperature sender on driver's side of block where it was working before the upgrade. It no longer works because it's wiring is incompatible with the Ron Davis wiring & or new spal coolent temperature sender.

2. The single factory electric fan was replaced by the dual spal fans & relays from Ron Davis. Leaving me with a disconnected a/c & ecm circuit that turned the original fan on-off at different preset's. That I don't know what to do with.

So questions are:
What kind of wiring modification do I need to make to get the a/c & factory temperature gauge working again.
So I can let the Ron Davis wiring, relays, temperature sender etc control the fan's?

Thanks in advance.
