I've got a set of fans from what I"m told was an 85 Sentra. Problem I am having is wiring them up. There are 4 wires going to each fan. 2 go in 1 spot, 2 in another. Can someone explain how these are wired up? I've run the black wire & a 12 volt source to every one of them and can't get it to run at all. Thanks for any help.

there probably is 2 wires going directly to the fan motor, a power and a ground, the other two may be for a thermostat that tells the fan when to turn on and off, you can either wire the fans to a switch that you control or you can buy a seperate thermostatic relay control kit, or wire the fans into the stock wiring.

There is no stock wiring, this is going into my hotrodded Chevissan (92 Hardbody frame). Anyone have the wiring diagrams from their Haynes manual handy? Maybe that would help.

Two wires are power/ground and the other two go to a temperature switch. You can just fuse the two temp. switch leads and then use whatever method you want to control power to the other two leads.
