Horn button with Lecarra Steering Wheel

Just wondering if anyone has dealt with this before... I just installed a nice LeCarra wheel and hub adapter on my 66 with the stock column. Everything fits fine, turn signals cancel, no problem.

The cool billet LeCarra horn button I picked up on ebay with the Ford logo engraved on it -- and which nicely conceals the 9 allen head bolts around the wheel -- has only one wiring terminal on the back... Hmmm. The proper hub adapter on my car has two wires. Why are there two wires? Do I splice them together and attach the single lead to the back of the horn button? This is apparently the wrong horn button, for that reason, for this setup. Apparently, LeCarra doesn't make this nice horn button anymore so no luck there. Just wondering if there's a simple solution before I start drilling, cutting, and splicing. Thanks!

Thanks everyone for the replies so far! From what I can find, the button's for a Ford (because of the engraved logo on it), but probably for a Ford with an aftermarket steering column (GM wiring). I didn't know this when I bought it...

I had figured both wires for the Ford setup were positive and pushing the horn button grounds them out and causes the horns to sound, but after reading the replies -- maybe not. I'll probably buy another button -- this one will be correct for the stock set up I have -- then take the new button apart and modify the nicer button to match... I will post pics when the interior is done.

The GM completes the circuit by grounding. Ford is completing the circuit by connecting two positive wires, continuity.

Not sure how that button is grounding, but if it's the body, you can't use it. If it's got a little bar on the side, modify it to just complete the circuit for the Ford wiring.

Thanks for the additional help, I think this clears it up. This button is a big honkin chunk of shiny metal. I think it is grounding through it's body right to the face of the wheel. There's a small threaded hole on the back to accept a ground screw and wire. There's a rubber strip around the body but I think that's just for a tight fit, not to stop any current... Well, I did order a black plastic horn button (smaller diameter, shows the allen head screws) this afternoon to look at it. Hmm I may have to use that one instead... Maybe I'll keep the shiny one for shows.
