Electrical Suzis are the electrical lines passing alongside the hydraulic lines (or air lines) passing from the rear of the artic tractor unit; and connecting the the trailer. Hydraulic lines used to be colour coded, but this is no longer tha case. Hydraulic lines operate the trailer braking system (in conjunction with the footbrake and parking break); these lines include an emergency hydraulic line, should the first fail.

The electrical connection lines operate the lights on the rear of the trailer, any running lines, and operates an anti-lock braking systems on the trailers axles. Electrical lines can also be used to power electrical auxiliary equipment; such as a tail-lift, or a HGV Box refrigeration unit.

Hope this helps.
