Question about what's behind the passenger floor panel

Car is a 1989 US 328. I'm trying to find out why my seat belt buzzer and key in/door open buzzer aren't working. I looked behind the passenger side floor board to examine the buzzer module, and found all this stuff! I know that some of it is for a Clifford alarm that hasn't worked in years, and some is stereo wiring that I also want to remove. I'd like to remove as much of that junk as I can. The wiring diagram and owners manual have a picture that seems to indicate that everything that is original should be attached directly to the back of the panel instead of stuffed into the area behind it. Is this true, or are there other items and wiring bundles that fill that space? TIA.

Thanks Brian. Everything that I can identify as part of the Clifford system or the stereo is coming out. I just wanted to confirm that most of that junk doesn't belong there before I do something regretful.

 

So I removed two Clifford black boxes and a whole bunch of stereo-related wiring, and was left with a giant wire bundle. Part of that goes to the relays and buzzer module bolted to the back of the foot board, and the rest of it goes to these big black boxes:

The two boxes are zip-tied together. Here is the writing on the top, which indicates they are factory modules having to do with ABS (car is an 89) and the air conditioner:

Many thanks! For some reason I didn't think to look at the parts diagram. Now I know what is in that box. Everything's been removed but what's in the picture, as you said.

 

Here's the "after" pic. The only things left in the compartment other than what's attached to the backside of the footboard are the antenna signal cable and another unknown cable, both of which route to the trunk area on the right side, so I'm keeping those where they are.

Bad news. Now that I've removed the alarm components and associated rat's nest of wires, the car won't start. All electrics work fine, fuel pump runs (I think) but the starter won't crank. I also removed the radio and associated wiring for that. But I'm wondering if the no-crank situation is caused by remnants of the alarm system still in the car somewhere, and by removing a lot of it is it possible I disabled the starter circuit?

There's a big wiring harness that connected to the alarm modules, and one branch of the harness went to a relay socket and relay that you can see in the middle of the picture in post #1 above. I cut a bunch of wires from that harness and also removed the relay since I assumed it would serve no purpose anymore. I've thrown away the alarm modules but the harness is still there and I kept the relay.

A quick web search has led me to believe that I might need to put the relay back in. But don't alarm systems usually disable the fuel pump rather than the starter? For some reason I was under that impression. Anyway I'll put the relay back into the alarm harness tomorrow and hope for the best.

 

That's true, but "don't fix it if it ain't broke" is a good strategy, which I violated. I should have said "fingers crossed" instead

You and bitsobrits are right, I should get in there and remove it all. But I'm smart enough to know what I don't know, and it'll be a PITA to do that. Since the car is back to normal running condition, I'd prefer to put that project off for a while. Best months for driving in Colorado are September/October so I want to spare the downtime. For now I'm just going to zip tie that alarm harness out of the way and make sure any hot wires are protected.

If you haven't guessed by now, the car started right up after I replaced the alarm relay in its socket. Pretty glad I didn't throw THAT part away.

All of you were a great help, especially Rifledriver as usual. Much appreciated!
