Has anyone installed a switch to turn on the electric fan? The previous owner of mine installed one, but it quit working before he sold it to me. I'm trying to remove it and there's one wire that I'm not sure if it's aftermarket or a factory wire. If anyone has a link to a writeup, Id appreciate it.
 
There is only two places that I am thinking the wire could go, to the power module on the passenger side, by right side kick panel or to the actual fan wiring it-self. I'm thinking green/orange or orange/green. Don't have my chilton w/me, buy one bye the way.
On the 99-00 Gts that wire supplies power to the Fan relay constantly from inside the passenger compartment, so that mod won't work from there on 99-00 Gts.
