Ok, Ive removed the cover to get access to the towing loom. I assume it is the bunch of cables with the connector on the end just under the cover. However there isnt a black cable like I was told by Lee GSI, there is brown, red, and a load of other colours with a black stripe down them.
At first there was no power to any of the points on that connector, however after I added a fuse into one of the empty fuse sockets the red is now live. However its a constant live, and I really dont wanna use that.
