Horn on aftermarket wheel

[Hotspurs85]

Right, got an OMP steering wheel on and the horn has decided days before the MOT, just my luck. The garage dont want to touch it in fear of setting airbags off. Its a 53 172, any ideas???

Decided not to work? Has it worked before? Check spade connectors/fuse. If they appear Ok, new horn form the scrappers?

I bought the car with the OMP wheel on and the horn working and over time it has just stopped working. The mot centre don't want to touch it and I'm struggling. Anyone in the Nottingham area with Knowledge or any recomendations please shout up as i'm now stumped
