Hi all, I'm new to this site, so apologies for jumping straight in and asking questions!!

I'm fitting a towbar to my Mondeo hatchback, and was wondering what was the easiest way to fit the electrical side of the install?

Happy with physically fitting the towbar, its just the electrics that I need a point in the right direction. I have the bypass relay and happy with how that interfaces with the socket on the towbar, its just where I need to be running the cable to within the car.

any ideas?
