Horn wiring - 78 Brat


Recommended Posts

I bought a new steering wheel, and modified the hub so it would fit.

 

It came with 2 horn buttons.....

1 with 1 terminal

the other with 2 terminals

 

there is one black wire attached to the "disc" on the front side of the hub.

 

There is another wire that the kit came with..... not attached to anything. I'm assuming it would be used with the 2-terminal horn button.

 

which is it?

How is it connected???

EA71 Brat horns IIRC are a switched ground circuit, with one wire. Typically, there is a little plastic plate under the hub with a metal ring in it that a wire fromt the column attaches to, then in the hub there is a wire that is held against the plate with a spring. The wire in the hub is then attached to a metal plate that is attached to the horn button, and when the horn button is pushed the metal plate contacts the hub, completeing the ground circuit. Also make sure the ground wire that screws into the column is attached.

THANKS!!!

 

I bet that ground wire is my problem. I got the car home in October of 2008.... and immediately tore it apart. I just recovered the dash and put it back in this pst weekend. I plugged all the connectors back, but remembering everything was tough.

 

Where (approximately) is that ground wire?
