I wouldn’t get the first party ford one, would get an one of the garages that just do tow bars to fit one. Yes you don’t get all the approved fitted eco engine bits but you will save money and a good fitter will do what they did with mine and fitted a fuse before it linked into the cars electrics so if the tow bar flips out it won’t effect the car.
I paid £175 from:

I booked it in the day before they had the parts and it was fitted while I waited, they did a top job just under an hour and haven’t had an issue since.
I drive a new shape C3 and we all know how bad French electrics can be, but not had a single problem since ive had the tow bar fitted.
I run a thule 2 bike carrier, with its own in built lights and place for the reg plate.
Ps I had mine fitted 2 years ago, if the rules have changed then ignore me.
