How to wire the horn on a momo steering wheel

[7gvr4]

Hey guys, got a momo gtr 2 wheel for my car just wondering how you wire the horn up for it, it's got the normal black wire in the boss kit and its also got a yellow/green wire that came with the steering wheel, there's a plate which gets sandwiched between the wheel and the boss kit that has a prong for one of the wires, im guessing that the yellow/green wire goes from the the horn button to the plate and the black wire goes to the horn, and can anyone tell me which wire goes to which prong on the horn button

Cheers
