Just did a electric fan swap on my 05 5.4 fx4, I'm having trouble locating a 12v switched power or ignition wire I can use to splice into for the fans relay under the hood. My year doesn't come with the clutch fan harness. Anyone have suggestions?

I read in a post where someone used their radio ignition wire for the relay for the efans

Any idea what color wire that is?

Do you have a stock or aftermarket head unit? If you have a aftermarket one tap into the one in the wiring harness going into the radio, so you can save from screwing up stock wiring harness.

Got my fans from troyer and they told me in the directions where all the wires were to tap into. Like the one for the A/C so when you turn on the a/c the one fan comes on. I think most of my taps were up by the firewall on the passenger side where those main harness plugs are.

Here's the part of the directions for that from mine.

I'd use one under the hood...Here:

There are two wires from my fans that they have you comine into one so that you only have to splice one wire in at the pcm. They have you solder it in and cover it with heat shrink tubing. Hope this helps

Thats exactly were I was saying in the Troyer directions too.
