Before spending any money, whip your airbag off (disconnect battery for a while first) and use a multimeter check for ground on the steering column.

Aftermarket bosses ground the horn through the column, and some early cars have a poor ground.

I never looked at how the OE wheel grounds, but that is my understanding others may know more (e.g. dammit had a lot of trouble getting his working).

I'm still somewhat baffled why this is is an issue. I've done three wheels now with the Momo boss and the horn is not an issue, even Stotty's car where his Tuna had spent (IIRC) four hours trying to make it work and failed.

If you're anywhere near Sandhurst, Berkshire, bring it over and I'll do it. I've done Stotty & knw911's cars as well as my own.

I’m a little too far away. I’m in Northern Ireland but I really appreciate the offer. I’ll give it a whirl before I’d be bothering anyone.
The info on here is very helpful though. Just helps with a lot of the head scratching and the wallet Grin

Seems like some bosses ground the horn through the column, and some use the OE wiring.

I suppose the thing to do is get one that is confirmed to use the OE wiring.....

Why not pop a "how to" up SJ so people can sort it if they encounter those issues? Thumb



Yeah that would be great! Mine works with the ignition off but not with it on which i believe its indictative of the ground fault.
Mind you its been like that for 18months now!!
