Re: Bought a new Steering wheel with Horn
Unless wires have been added by some PO, there are no wires for the horn above the turn signal switch.. The ground wire for the horn relay windings is in the turn signal switch harness.. The turn signal switch has a brass spring-loaded button sticking straight up.. The brass ring on the back of the cancel cam contacts this button when the cam is installed on the steering shaft. On the top side of the cancel cam is a tubular part also sticking straight up. It has a twist lock connection similar to a small bulb socket. This protrusion passes up through a hole in the stock steering wheel and rotates with the wheel.. Another spring loaded button fits in the socket of that protrusion. The horn button, its contact ring and cup are all held in place by three special configured screws. When the horn button is depressed, the horn relay is grounded through all the above described components, down through the ground wire that goes to the horn relay.. If all is properly functioning, the horn will blow...
This is how all the factory designed components come into play.. If you have an aftermarket steering wheel, you'll need to follow the instructions that came with it to explain how and what parts are necessary to complete the installation. Without those instructions, it's anybody's guess as to how it is assembled. Some pictures might help...
