Trailer harness is connected directly to the rear lights
A relay will only operate one circuit and there are 5 or more separate circuits for a tow bar

Cant find the towbar electrics plugs for x-type

I assume that the towbar didn't come with a proper wiring kit as, unfortunately there is not a specific connector for the towbar wiring on the x-type, the proper Vehicle Specific Kit plugs into the rear light. There is a power connector with three pins on the left and a grey reverse sensor cut out connector also on the left. but you will either need to use a Vehicle Specific Wiring kit (about £175) or use a bypass relay system.

I need to fit towbar electrics to my Focus C Max 58 plate, where do I begin?

You can wire directly to the rear light wiring behind the trim carpets on both side, however you must use a bypass relay system on the indicator circuits as the flasher unit overloads and switches off if more that 1 extra lamps are connected. Best use a test lamp to check which wire does what.
