I’m in the middle of this same exercise myself and found that right behind the radio under the dash worked well for me. I really wanted the PCM inside the cab but with the vintage air setup I could find no way to mount the PCM on the passengers side. I have a gen III PCM out of a 2006 Silverado and am using a retro auto sound stereo. It’s only mocked up right now but I think this location is going to work out pretty well.

I reworked the factory harness and there is plenty of wire to place the PCM in this location.

I’m in the middle of wiring now and will take a picture tomorrow and post it up.
