I'm rough installing my DC controller for my E fans. My questions are.

1. Where is a good place to get 12 volt signal power when the ignition is on? So fan controller turns off fans when ignition is off. (On Battery side)

2. Where is a good spot to connect to the AC (Which wire) at the plug on the compressor or in the fuse panel inside the cab? So controller gets signal power to turn fans on with AC.

Going to install the fans tomorrow but want to have everything pre-wired for the install. I have to make mounting brackets for my fans tonight at work for the install.
My truck is a 2004 FX4.

Thanks.
