Not that I know of, but if need be, I can swap mine out for a 8625 and load your bin. Not gonna happen today though, it would be several days before I had time.

I'm fixing to go out and wire in a couple lights the ecu and do some more testing. It was getting too cold last night to do the wiring.

looks like my volt meter must not had enough resistance or something. it appears to be working with the relay hooked up.

now that is what i want to hear. glad you have it working. let us know the progress as i want to use the schematic i posted and have the ecm run the fans, engine, and the 60e.

With yours C1 will go to E3 (Fan A), this will be high speed with both fans running. Connect C2 to E7 (Fan B), this will be low speed with just the right fan running.

If you want to use the soft start for high speed, then replace the Cool Fan 1 Relay with the Hella solid state relay. The relay connections will be like this:
wire B1 to pin 86
wire C3 don't use
connect pin 85 to ground
wire B3 to pin 30
wire C1 to pin 87

you are the man. i have this saved to my camaro info folder. man i love this sight. but one question. in the diagram i posted when the first relay (or temp threshold is reached the fans come on low) the first relay hits the power on both fans but there is a croosover wire that causes them to run on about 50%, then when both relays ( second temp threshold is reached) both fans come on high. so will these grounds from the ecm come on consecutively, or is it one or the other.
