Head unit wiring HELP

i just installed a new head unit in my truck. the wiring of it is a little fishy. i have a 99 Tacoma that already had a alpine head unit in it. does anyone know a good wire diagram? or know why the stereo wires have anything to do with the door locks not working? im going to try to get some pictures up for some help.

what im really having the problem with is the memory, door locks, and the correct B+ wire and ACC wire. thanks for any help you can provide.

 

when my stock head unit blew out, it was blowing fuses that also made the door locks, and dome light quit. To me it's worth it to just have an audio place do it. They told me that some different head units require different wiring harnesses, and i'm not good with wiring so i just had it done. I would just ask them for some advice.
