Van beeps in series of five when I start it and air bag module light does not work?

My van started beeping five times when I started it and I've read online that this is due to an issue with my SRS or airbag module. My airbag module light does not appear on the dash at all so I figured I needed to change the bulb since that's what I seen a lot of people online saying, but I changed it out and it still doesn't turn on and the beeping is still there. I'm in the process of converting this van into a small camper and so I removed wiring in the back that led to accessories I didn't need and took it out, such as a powered bench seat, tv, and radio. I'm not sure if that somehow would have tied into the SRS or if any of the wires for it leads to the back of the van? I've checked the fuses and none of them are burnt out but when I remove the fuse five the beeping stops, which is the fuse for the airbag module, if that means or tells anything. I haven't messed with any wires at all beneath the dash, and when I removed my drivers and passengers' seat to replace the carpet I removed a cigarette plug box beneath the driver's seat and then plugged everything back up afterwards. I'm stuck and cannot figure out the issue, so any help or info is appreciated. Thank you!

So, what happens is the airbag module or the spiral wire behind the steering wheel goes out. Here are the wiring diagrams so you can see how the system works and which wires to test to make sure they are working. Also, I have included the module location in the images below as well. Start by checking the fuses.

They call it a sliding contact. Check out the images (below). Please let us know what you find. We are interested to see what it is.

Thanks for the diagrams and for getting back with me. So, I did start with checking all of the fuses beneath the dash with a multimeter and they all came back with voltage readings besides fuse 7 and 13. I pulled out both of the fuses to see if they were good and they looked fine, so I assume it's because they're in nonuse?
Also, I did inspect all of the wires beneath the dash leading from the airbag diagnostic monitor and fuse box and none seemed to have any damage (i included photos below). I'm not 100% sure which wires to voltage test, I circled all of the ones I believe I'm supposed to check but I wanted to ask first before I unplug anything.

Thanks for the images, everything looks okay but before you start testing or removing anything undo the negative battery cable for 1 minute before work begins.

Okay, the image you shared up above says the positive battery cable, does it actually matter?

I went ahead and removed just the negative battery cable and tested all 4 plugs I circled and got no reading on any of them. I'm not sure if thats because i'm testing them incorrectly or if the air bag module is bad and causes them not to work. Any info or advice is appreciated, thank you.

If you are getting a good ground and power inputs the module is bad. I would replace the module.
