Wiring - Spare Plug ID

[addo]

As a self-confessed factory options tart, I refer both to my pre-multiplex Berlingo, and the following picture. (Click at risk of pop-ups and light grade malware...)

Based on other PSA cars I am guessing the two five pin plugs that have dual earths, are the passenger window switch and one-touch driver's switch.

The larger white plug has me puzzled though. I am of the understanding the RF remote is fitted forward of the OSR wheel under that black metal tray, beside the central locking control box. My radio is under the flip flap below the hazard and A/C switches.

Any suggestions would be helpful!

Thanks, Adam.
