I have read plenty about switches and what not for dual fan setups, but I got a 91 RS with single fan. Where is my fan relay? What do I wire the switch to? How heavy should this wire be? Should I fuse it? Am I completely retarded?
I might just wire it so the fan runs all the time when ignition ON. Who knows. But I really need to know where single fan setup relay is, and what should I jumper together. Thank you!

 

I can only speak from my experience i have a dual fan setup. my fan relays were on the drivers side firewall under the hood. u need to find the relay it should at least have 4 to 5 wires going to it. there should be two really thick wires orange and black. u can get rid of he relay which is the black part with male plugs. and hook the switch up to the female connectors on the two thick wires. you should be able to turn the on and off without the ingition on.

 

The fan relay is right next to the master cyl. on the drivers side firewall. All I did was tap into the green & white wire, run the wire to one side of a switch, and run a wire from the other side of the switch to a good ground.
I used 12 gauge wire. It took about a half hour.

And with the switch turned off, it works the same as it did from the factory.

 

Thank you. Your help is quite appreciated...

 

here's a pic.

 

Sweet. Thank you! Now I just gotta go do it...

Looking in Chiltons at the wiring diagrams. I should just be able to ground out the dark green/white wire (with a switch inline), and that would do the trick, right? How heavy wire should I use (switch too)?

 

Yes the G/W, thats the wire I show going throught the firewall (I bought some stock wire sleeving so it wouldn't look like a bodge job!)

I used 16 gauge wire to be on the safe side and a standard switch. You're not pulling big feeds through this set up, just running an additional earth with a switch in the middle, so you don't need extra relays and stuff.

 

The original owner of my T/A did some wierd *** wiring to mine. It looks like he's got one wire directly to the fan, one wire grounded, the one from the fan goes to a toggle switch underneath my steering wheel, and the other wire on the switch is connected to the positive battery terminal. Wtf? On top of that the dumbass used electrical tape to connect wires so I had a small amount of smoke coming from underneath my steering wheel and come to find out the electrical tape was burning up.. Lol so I replaced all the tape with wire nuts.

 

soulrev,

Keep watchin' for smoke.

 

I don't like wire nuts for a car either. They tend to loosen with vibration, and they rust which can cause bad connections. Use heat shrink tubing, and solder the wires together, then shrink on the tubing to insulate them. Otherwise, as UK says, keep looking for smoke!
