any wiring under front seat raised platform?

[workingonit]

Once again, I'm making an addition to my X5 equipment, not sanctioned by BMW. I need to screw into the raised (angled) platform formed by the sheetmetal brace under the front seats, in order to install a "Framed Stretch Mesh Net Pocket" under each front seat.


The pockets will retain a first aid kit under the passenger seat (there's one there now, but it slides forward under braking), and a lock-box under the driver's seat. A secondary function will be to secure my aftermarket (cheap) floormats in place (I do this on all my cars, but drilling holes in the BMW is worrisome to me).

From the only photo I found,

the only object under that metal is a HVAC duct running to the rear. A screw-hole thru one wouldn't hurt, but if there's wiring, it could. I see no wiring in the picture, so is it safe?
