Location to pick upa/c contol wire 4 e-fans
I'm in the planning phase of e-fan install. I plan to mount my relays behind the glove box. Can I pick up the a/c wire somewhere in this location. My trk is an '04 xcab; what color will the wire be and location, if anyone can help, thanks fellas.

If you want the signal from the AC clutch relay, you should be able to get this at the PCM / Aux relay box ( under the hood ). It is a ground trigger.
The AC clutch relay coil is powered from the PCM power relay, the coil ground is supplied by the PCM. It is the Pink with Yellow stripe wire.
If you need the trigger to be power, you can take the output of the AC clutch relay, this is the Gray w/ White stripe wire from the Aux relay box. This is the output of the normally open contacts on the AC clutch relay, and is the same circuit that the AC compressor clutch diode ( cathode side ) is connected to.
