Buzzing relay

I have a really weird problem. I have a relay that is buzzing that is under the glovebox area. I think it is the theft relay. I tried replacing the relay and the new one just buzzes louder. I am going to try and describe when and how it is working. The car wont start with it removed. When I start it, and it is in park or nuetral with the doors closed, the relay buzzes and the overhead lights on the rearview mirror are on but a little dimmer than when the door is open. When I open either of the doors, it stops buzzing and the lights are on at a normal brightness. When I put the car in drive or reverse or any other drive gear, it stops buzzing and the rearview mirror lights go out. I tried taking out the door light switches and as soon as I finish unthreading the switch from the jamb, it starts buzzing, but as soon as I touch it to the door jamb to ground it, it stops buzzing again (with the door open). This seemed to start happening when I put a new radio and front door speakers in the car. I tried unplugging the radio from the harness and it still does this. When the radio is in turned on but the volume down, and the relay is buzzing, I hear a slight buzz coming through the front door speaker. Does anyone have any idea what my problem is? Sorry this was sooo long, but I thought I would give as much info as I remembered about this. Oh, by the way, the car is a '95 Camaro Z28

Here are the locations of some pics of where it is at.

Re: Buzzing relay

Probably the theft deterrent relay (TDR), since it won't start without it. The other relay is the hatch relay. If you did not have these issues before the stereo install, I think I would attribute the problem to some wire that was incorrectly tapped into.

Re: Buzzing relay

I was thinking it would be it also, but I unplugged the stereo from the harness and it still was doing it. My next step is to unplug the front speakers and see if it still does it. Any other ideas? I wondered if it could have something to do with the fact that it was a factory bose system and I put another radio and 2 speakers in place of it. I thought I read somewhere about these systems being tempermental.
