Cabby electric window control module

Hi guys, I'm half way through fitting a set of cabriolet electric windows with 1 touch wiring but can't work out where to mount the control module.

Does anyone know where the module goes? Are there any mounting holes or do I need to get a drill out.

Think I'm sorted but if anyone knows for definate on UK cars please share!

I've just redone the wiring harness for mine, as they didn't have relays fitted.
I have fixed the grouped relays to the bottom of the heater matrix casing with a small bolt to hold them facing the cabin, should I need to test a relay at some point.

Mounted on the driver side under the dash. I'll grab a pic when I get in

as promised
