seat control wiring looms anchoring pin/screw location

Hello all,
Vehicle: 1999 Porsche Boxster
Issue: One of the seat control wiring looms has come loose from its mounting point and is getting caught in the seat rails, which causes the fuse to blow. When I manually free the loom, everything works correctly.

I’m trying to determine where this wiring loom is supposed to be secured to the seat. The loose loom has a plastic push-in expanding rivet, but I’m not sure where it should be installed. I’ve checked the parts catalog, but it doesn’t show this specific component or its mounting location. Does this mount to floor pan or the seat frame?

Please see the attached photo—the part in question is circled in yellow
Thank you for your time!!

Now... I'm no rocket surgeon... but wouldn't one of those two holes next to the yellow circle be obvious? I'd plug it into one of those holes... purchasing a new piece if the part is a little wonky.

Not even close. Those holes are the seat track mount.

LOL. I thought it was too obvious, and figured if I was incorrect a brain would chime in.

I was like, "The seat tracks are nowhere near those wires."

Thank you, Mr. Ladd.

Okay, I figured out where it goes. There’s a small rectangular hole on top of the plastic PAS alarm control unit, and a peculiarly shaped metal fastener fits into it. The wiring harness screw pushes into that fastener. The screw is damaged and keeps coming out. None of these parts are listed on the PET diagram that I was able to find
