I'd like to run a switch to power the compressor manually. I'm ok with electronics as long as I know where to start looking. has anyone done this in their truck? where would I look for the power wire for the compressor?

You may have already ruled this out, but one thing you can try is replacing, swapping, or tapping the A/C relay. From what I can tell, some of the factory relays they used are prone to getting stuck and causing problems
This happened to me, where the A/C light would randomly start blinking and the compressor wouldn't kick on. I was in a hurry in the summer and didn't have time to grab a new relay, so just gave it a few good taps against the hood to knock the arm loose and it's been fine since
