Help ID this wire. Non standard?

[D5RSR]

I've taken out the rear deck carpets to dry them after the wiper seal has failed and there's a cable taped across the rear. Looks like a 2 wire that's crimped on the end. Doesn't terminate on anything. It crosses the rear deck and goes under where the control, units are. I'll strip it back further see where it goes later.

Doesn't look to be standard fit, any ideas?

Tracker

Traced it back to what looks like a phone kit or tracker box.

Yes looks like a tracker and that wire you've got is the antennae.
