Does anyone have a schematic for the wiring of the dome lights/key ignition warning buzzer/door ajar switches they can post?

I am having a problem with the battery being drained if the door is left ajar overnight in the '82 TD. Also, the buzzer stays on whether the key is in the ignition or not. Not sure, but probably related. I suspect a problem that I caused when I accidently pulled the ignition switch plug apart while changing out the lock/cylinder a few months ago.

Also having a problem with something connecting through fuse 8 (compressor/blower/evap temp sensor) drawing too much current, and not sure if this is related, too)
