Those three are decent to get you an idea. DO NOT JUST TRUST WHAT THEY SAY. TEST wires with multimeter, NOT a test light.

Heres a link to a bunch of different alarm install manuals as well.

Here's a link for disassembly of radios. Just put in the car and download manual for the mounting kit, and it will tell you how to take it apart for most cars.

And i'm just throwing this out there... if you're going to hook a stereo up that has hacked up wires, or are even THINKING of putting in a remote start system.... buy a multimeter and learn to use it! Also twisting wires and electrical taping stereo connections is NOT an acceptable way to do something. Solder, or at the very least use crimp connections!
