Hi Folks ,
I see someone has done a diy and it works , tried it myself and bingo worked. The problem I’m having is getting the spade to stay on the other part that’s attached to the roof. Pics below. The female lug is to big and keeps slipping off , have circled it in red, any advice ??

The other side is ok as fits perfectly.

The female spade it to big for the male part here

This fitting is ok as the female lug is big enough to go over the male.

 

Squeeze it with some pliers.
