Mystery accessory wires under dash?

[Marco W]

Hi gang,

I’m beginning to remove a bunch of disused accessory wiring installed by previous owners, or from the factory in my ‘96 E350 EB SMB. There is a LOT. It’s a serious rat’s nest under the steering column! I’ll try to get a pic but it’s a tough place to shoot.

I ran across these two little guys and I can’t figure out what on earth they might have been for. Not labeled. They are like tiny coaxial cables, with really thin wire — like angel’s hair pasta or maybe kitchen string. They disappear up into the dash alongside the doghouse (driver’s side).

Any ideas? Also a pic of my dog, just for fun.

Thanks, Marco
