My (aftermarket) radio was wanting to fall out of the dash and when I pulled it out, I found this plug that does not go to the stereo. I don't see the male side, but I want to be sure I didn't mess anything up before I shore up the stereo bracket. and close the dash back up.
I bought this car because I like the look and feel of it but I have never been a full-on Toyota enthusiast, so I am not 100% sure what I have or don't have. Is there a good resource I can review before I post this so I'll be ready to answer all the questions anyone might ask?
