Help installing Ford horn

[mr.mitsu]

So basically I grabbed this horn from the scrap yard.

Notice there is only one plug and I assume it gets grounded from the centre mount.

Now, here is what I have

There are 2 connectors going to the horn. One wire is constant "hot", The other is ground.

When I try to install the Ford horn by connecting the constant 12v (ACC)and mounting (ground) it to the chasis, it automatically gets tripped.

I've read some horns are activated by grounding the circuit. How can I wire this to work in my car?

Thanks guys /ubbthreads/images/graemlins/smile.gif

best thing to do would to have your ground costant and wire the power side into the horn switch.
