Tiger 800 Replacing Aux Electric Socket

Hi all, i am after some advice, as i managed to snap off the plastic water proof cover on the aux socket on the front of the bike next to the ignition key point.

I have a replacement unit, but when i look from above, i cant just remove the old one out and from beneath the access to the nut holding it in, is extremely limited.

Any advice on how to change it, as it is driving me bonkers trying to figure it out?

Cheers
