Hi guys I want to fit a towbar ,it comes with a universal wiring kit and it seems it need a bypass relay to be connected to the Mondeo. Anyone as any experience with this ? Do I need a canbus for my model of car?Thank

The canbus monitors the bulbs in the vehicle and trailer if you use the dedicated loom.

With a bypass relay the relay takes a tiny amount of power which the bulb failure system

will not notice.

The cars canbus will not monitor the trailers bulbs with the bypass relay.

Thank you very much for the explanation, any tutorials on how I go by connecting the Bypass to the lights wiring? Is there a diagram of the wiring to the rear bulbs showing which one is which by colour? Thank you
