Installing electric fan need help

[86Cutlass383SR]

For dual fans like the LT1 or LS1, you would need 4 relays for low, high and tandem/AC/over-ride operation. I would need to draw up a quick diagram to be sure...I had one on my desktop but I can't find it-I need to go through my electrical folder and I'll post it up here...

Please do. I'm running the 88-89 f-body dual fans and I can't find a good schematic to wire mine up. Are these f-body dual fans single speed or 2 speed? I've had them wire up but wasn't real happy with how I had mine. I am using a Howell TPI harness but it doesn't incorporate the electric fans the way the factory does. A write-up on ThirdGen.org says to disconnect control from the ecm for better control anyway. I used a seperate Howell dual fan harness but wasn't really satisfied with it. It was basically one fan hooked to the head temp sensor and another wired into the a/c. Basically two seperate fan systems in one. I'd like them to work together like they're supposed to. Primary fan comes on and then the secondary comes on for additional cooling if needed. Then when you turn on the a/c it turns the fan(s) on. I'd like not to have to remember to turn them off/on.
