stock radio not working, after fender bender... Options

[LimitedST]

awhile back i got in a wreck, and the radio was working fine. But at the wreck, i had the lighter thing unplugged, so i had to take apart all that crap to plug it in so i could plug in and charge my phone so i could call the police and what not. anyways. Now that im working on the car and its back from the body shop, i was gunna put the same CD in both my cars (5th gen + 6thgen) and see which one sounds better , both have aftermarket systems, but my 6th gen has stock head unit. heres pics. i think everything is plugged in right, but it wont turn on, no cd player, no radio, no nothing. only thing i can think of thats not plugged in, is the lighter thing again, because it fell out in my garage sumwhere nand cant find it, but i would think it would still work since it worked the night of the crash without it plugged in. heres pics.





whats this white plug for? its not plugged into anything (ever never ever) and it was taped downback on the other wires to keep it out of the way.

i found em. left of the steering wheel for the interior, and the ones in engine bay kinda hard to miss, but how do i know which one ifs for the radio? and how do i check if their good or bad?
