i can't even find a pic of it to show you because i don't know what they are called

but

i've just bolted a tow bar to the mondeo because i'm expecting to use it to tow stuff with but i needed to get the wiring sorted

not a problem, you get wiring specific kits that just plug in and away you go

but i can't figure out what them little plates are called that go between the tow bar and tow ball and the plug for the wiring is secured to

anyone help? it's doing my nut
