How to wire my garage door remote to the horn button on my motorcycle?

This guy solved the problem with it's own approach :)
But take a look at this approach also

Do you want it to still work the horn also.  If so you'll have to change the switch or put in a relay.  Then the switch closes the relay that honks the horn and opens the garage door at the same time..  Your horn works on 12 volts (probably) and you gd opener works on 9 volts (probably).

If you don't need a horn then just wire the switch in parallel with the switch on the controller.

I would just add another switch to the motorcycle and wire it in parallel with the opener switch.
I'd wire it in series, so that the horn provides a sort of voltage drop for the less-needy garage door opener.
I wouldn't. In series means the door opener limits current to the horn.

Parallel is a better answer, with appropriate regulation if you need to drop the voltage for the transmitter. Relay, or a separate switch, is probably a better answer than that.
horn first! Then the horn limits the current to the opener.
Anyway, it's a sight easier than going out to buy a relay just for this.

<a href=""></a> is a nice solution-- although a little pricey. You set it up so that you can flick your high beams to open the door. I guess you could also hook it up to your horn.<br /><br />Make sure your headlight is straight up 12 VDC. My headlight voltage had an AC component and it didn't work.

Without knowing make/model etc., a motorcycle expert isn't going to be able to help you.  For some very general guidance, though, you can do it through a relay.  Make sure you use a non-latching relay.

Opn up your garage remote (or buy a spare!) and look for the terminals on the momentary-contact button.  Solder two short leads onto those terminals, and connect them to the "normally open" side of the relay.  On your motorcycle horn, find one of the two leads connecting to the horn.  Cut that lead a bit back from the horn, strip the two ends, and solder them to the contact (input) side of the relay.

Now, when you press the horn button, the relay will be energized (and the horn will still go off), which will close the switch on the output side.  That will act just as though you had pressed the button on your remote, and should trigger the garage door.  When you release the horn, the relay will de-energize and open the switch.

Obviously, with this setup if you press the horn multiple times, it's just like hitting the remote button several times, and your garage will do a little dance :-/
