LS1 dual fan harness questions I have a 2000 Camaro LS1 engine harness and have the dual fan setup for the same. Except I do not have the harness that goes into the fans. Are there other cars or SUV/trucks that have this setup?
From what I understand my engine harness will plug into the fan harness because its controlled by the PCM. I've looked on Ebay but cant find it yet.

No.. the Fan harness will be connected to the fuse and relay box.. and not the engine harness. You would have to use the required and body harness / Cxxx connectors / front harness to have the ECM control the fans.
Or you can control the fans with a standalone relay setup and then use the two ECM pins to activate the relay/fans.
suggest you research in the FAQ / sticky on how to wire up the relay and which pins of the ECM,

You should be able to make your own very easily. You will just use the 2 wires as stated coming from the computer. They should be green and blue. I went to the local scrap yard and $8 later I had the connectors for the fans. GM uses the same connector on many on the vehicles with electric fans. I then ebayed the relay bases and relays. Not too hard to wire it up following the schematic. Just fuse it as the schematic shows.

Going to go to the yard for the connectors and then check ebay for the rest. I think I read more in the past week then I ever read in school.

I used the harness and connectors from a f-body donor. I used some spare 30 amp relay with relay bases and just wired them up like a stock f-body. Did not take long nor did I spend much at all since everything was from the donor. Only cost was some new connector terminals.
