Hi,

Picked up a '88 Trans Am that I would like to use as a temporary driver

Would like a simple explanation of wiring a toggle switch to the fan relay on a '88 Trans Am. The car was originally a 305 thottle body, and now has a crate 350 with no heat sensor screwed into the a head to monitor fan control. Looking underneath, on the lower right side of the fan, there appears what looks like a relay.

Does someone know the color code for the wire to splice-in a toggle switch hooked to 12V to get this fan to start working?

Thanks for any response.

 

should be a ground, not 12v to trigger the relay. got a green and white wire coming out of the connector? try grounding it with the ignition on.

 

Green/white wire to grd, thanks for the response.
