Radiator Fan Wiring ?

[02pnygt]

I have an 02 Mustang GT that I am looking to run a switch on to override the cooling fan. I have read that this can be done by splicing into one of the wires out of the computer harness, running it to a switch, and grounding the other side of the switch. Problem is I am not sure which wire in the harness I need to splice into. Anyone happen to know what color code wire this would be for an 02? Any pointers to look out for?

thanks

Its the LIGHT-GREEN wire with the purple stripe! Terry

Thanks for the answer. Let me ask this. Do I have to splice into it by the computer or could I also do the samething where the wires plug into the rad fan and just run the wire back into the car? I ask because it would be alot easier to acces there.

You can get to the wire in the passenger inner fender coming out of the ccrm (constant control relay module) module I think.

thanks again. I was looking at a wiring diagram the other day. Looked like the wire ran from the ecm to a relay so i would have to tap into it between that run. I have the inner fenders wells out of the car so I will take a look.
