Urgent! Horn wiring problem. Cant get a ground from boss kit????

[saint_matrix]

Hello, I have an aftermarket steering wheel and am having troubles with my horm.

Usually you run one wire from the copper disk on the back of the boss to one of the horn buttons, then you ground it to the boss kit.
That was working for a while then it suddenly stopped? Now none of the boss kit OR steering column is ground? Does anyone know whats going on or if they can help me. I have to have it ready by 4:30pm today as I have a canary and today is the deadline. Thankyou

Thats weird...Do you have power from the copper disk?

Yeh i have power to the copper disk the only problem is that the steering column isnt grounding for some odd reason. The ignition casing around the key etc works as ground but the steering column wont.

Then why not just use the nearest working ground?
