Wiring switch to radiator fan
i have a 92 bird with the 3.1. Trying to wire a switch to the fan and because the fan comes on 225 and i want it to come on earlier. I cant seem to wire it directly to the relay for the fan to come on. Any suggestions?

You can try an adjustable fan controller they cost around $30 I have one on my bird works good.

Re: Wiring switch to radiator fan
my fan does not work by itself. it should come on with the a/c but it doesn't. I do know that when the green/ white wire for the relay is grounded the fan will kick in. I'm sure its my cts but idk where its at. so I just added a switch to ground that wire.
