Anywhere you like, try cleaning the surface.

Yes well tried to earth it to the body via the Earth back the middle pin and blew the fuse.
I have some time tonight to sort it out. Any ideas?

Ok, fixed, took it to a auto E and luckily he was on the ball with landies. Turned out it was hooked up to the fog lights earth.
Any way it's fixed now.
