Thanks for coming back the connector is squashed so pic nbg.
I'll just have to go over the wiring diagram again its the only connector that has a yelo 5amp flat fuse inside.
Saw it at greg morris shop he didnt know what it does but suggested intermittent wipers may be its job, he is very busy might have to pop in see him and trace it and let you know.
2 purple wires passing thru the fuse inside the connector....cheers
