Can anyone tell me where I can get a wiring diagram from to wire a 7-pin socket to a 2020 Fiesta.   Also is there a wire available in the wiring loom for a live feed to the relay, rather than having to run a new feed form the battery.

Hi,

Wiring a tow bar 7-pin socket is normally pretty generic. I have had a quick look and am struggling to find a fully comprehensive wiring diagram for both the car and the pin out. Please find below a wiring guide a friend has used before to do a tow bar 7-pin socket in case it helps in any way.

not neccersarily, ford require the fitting of a towing module to the car, if you do not fit this to the car, the car will start haveing weird random electrical issues using a standard 7 pin wiring kit

Hello @Baz52, as has been said by @Neb_engineer you need a Ford towing module and the BCM software configured.

Long gone are the days when you could just use Scotch Locks and splice in to the wiring harness. If you do that now on a 2020 Fiesta you will cause Canbus faults. The cars current monitoring will see the added lights as a fault,

Thanks for the replies.  Much appreciated.  Although I've fitted the tow-bar, I won't be rushing the wiring at the moment.  Only using a small trailer for trips to near-by council tip.
