wiring for 92 buick lesaber + more

i need a wire diagram for a 92 buick le saber. my problem is: i am putting in a after market cd player. have already CUT the factory wires and have not put the cd player in yet. i started the car to carge the battory. BUT, not the interior lights dont turn off when the car in on and/or the door is closed. plus the door dinger (the ding u hear when the key is in the ignition and the door is open) only dings when u fist close the door, to make it stop i have to open and shut it. AND, when i open the door the heater restets itself. the only things i have done are. 1: replace the factory speakers (all of them), and 2: removed the facory head unit.

The only thing i can think is the problem is the wires that i cut off of the factory head unit have some control over the problems that i have.....but that makes no sence... please help!!
