towbar electrics

hi all, ive picked up a towbar for my vectra C
ive installed the main frame part.
and while i was cleaning up the socket support plate and bumper protector plate in a electrolysis bucket.

i decided to test the electrics out.

wiring came in two parts...

plug that goes into the rear fuse board

and the 7N socket with the 7 core cable.
the two cables where joined together by a strip block connector.

yes i know what...
