03 Montero Radio Power Source question.
 

Help! I took out my stock stereo today to see what kind of wire harness it has and when I put it back it, it didn't work So of course I took it back out to see what I screwed up, well everything was plugged in but at some point the other end of the power source became disconnected from the car and now I have nooo idea where it goes! I've spent a couple hours looking for it and can't see or feel it anywhere. Any ideas??? Thanks! :confused:
