This is a bit weired, the washer motor on the bottle has 2 wires (which is 2 core 240v cable)

This travels from the washer motor all the way through the bulk head, through the car and connects up to a power and earth from the rear right light cluster!

Obvious it's a grand bodge, but anyone got any ideas why this is like that, and where they should really go!.
btw - the washer work fine LoL
