And thats another point that dhh3 got me thinking about with the pinched wire suggestion.
How good of a job did you do splicing the aftermarket radio wiring into the adapter harness?
Its possible, smashing all that wiring together as you pushed the head unit into the cavity and tightened it down, that you shorted or disconnected a weak or exposed splice, causing your problem.
There are plus's/minus's to soldering wire splices, I do it and use shrink wrap and wrap electric tape over the shrink wrap. Only drawback it makes a brittle section in the wiring, with lots of movement that might cause problems later, I have yet to have something go wrong, but its possible.
Look over your splices again, maybe reconnect the aftermarket radio and shake, squeeze, twist the section of wiring with all the splices, see if you can induce the short, reconnection, etc.
