Horn problems

[steviegsi]

Got M.O.T tomorrow, and the horn has dropped out of the steering wheel. It is one of those stupid aftermarket wheels, and on the 'horn push' the wire is still connected. I've had the wheel off but i don't know where the other end of this wire goes to? nothing stands out? anyone any ideas? please.....:confused:

sounds like its the earth that goes between the boss and ur steering wheel if that makes sense
