How is the M535 alarm unit mounted?
 

Hi All, I took off the seat yesterday and noticed the alarm unit is just hanging on its harness but is not mounted on the floor. I'm pretty sure it should be affixed somehow to the floor but I can't see how, looks like something is missing. Could someone chime in with some details? Thanks!

Lighter and 10 mm socket is gratis :)

There is a plastic screw on one side and a tab that slips under a raised area of the floor on the opposite side. The plastic screw is often broken off.

OK, thanks, so probably nothing is missing. I'll take a second look.

I can see both the retaining tab and the screw head in your photos, so everything should be there....

Good eyes, nothing is broken, they just didn't replace it previously. Now it's securely mounted.
What is this handwriting on the unit/? Could it be from the factory? Or it was repaired at some point?

Don't know, could be a replacement unit.

Does that number look like part of your VIN?

Nope, no match. What does that tell you?
