Look here for help first!
The two obvious horn contacts just trigger a buzzing sound in the passenger engine bay. I disconnected my battery for a few minutes to stop this. The horn itself had no continuity, so I started by installing an off the shelf generic replacement. Next step was to order a button for $1 from thailand off the web auctions by searching horn button.
I had the plastic shrouds off to fix the hazard light switch. (After popping the switch out there's a metal bb that dislodged from under the spring, simply inserted some lithium grease on the end off the spring to hold the bb in place and clipped the switch plate back in. Sometimes I get a right turn flash and have to jiggle the switch to get both. Originally got nothing)
Here's the horn button installed. The Green/red wire was wired in from where it enters the steering wheel. added a bit of insulated electric wire and a twist on wire connector cap to tie them together, then into the button. There where 2 white black wires in my bundle. One was a larger gauge. The other turned into a solid black wire on the other side on the connector then split into two wires as it entered the steering wheel. The smaller wire that turned into a black wire was the proper horn ground. I removed the insulation a bit at the connector base and tied an aftermarket wire in and re insulated the splice with duct tape to prevent losing the ground for whatever they doubled up on with this ground point in the steering wheel. then into the button with the other end.
There where also two green/red wires. The proper wires are the fifth slot in on the smaller connector. they correspond with one another, White/black turns into black on my connector, it was the smaller gauge white black.
I used a drill bit to drill the hole then enlarged it with a round file. Then remembered I had a step drill bit after the fact.
Here's a pic of a cake.
