I searched and found something about a head phone jack and a switch??

Do i just find a jack that fits the rear of the profec B and hook up a 12v switch to it??

 

I did a little write up on it.

Let me know if you have specific questions.

Thanks so much

 

That'd be sweet to do on steering wheel mounted cruise control buttons. I never use mine. Or if you have radio controls on your wheel you could use those.

 

would it be possible to use only one of the horn buttons for this, while keeping the other horn button in use?

 

Nope, they are hooked together.

 

I have a question about it. Will it handle the 12 volts or do I need to step it down in one way or another? Any chance you have a pic of what the wiring should look like? Or what goes to where? I'm not that good with electrical if you can't tell.

 

Since the two horn buttons are hooked up together, can't you just isolate one button and have the other one activate the switch?

How are the two buttons combined?

 

The buttons are in series in the wheel itself. No you cant isolate them.

To answer the above question....yes it can take the twelve volts.

 

if the horn switches are in series, then you'd have to hit them BOTH to get the horn to honk.

?

 

Oops...meant parallel

 

So parallel huh?

Can't you just keep one side wired to the horn, and have the other one run to the switching relay? I'll have to check this weekend if it works... hehhe

 

i'd rather just have a switch under the dash somewhere

 

That works too. Although a pushbutton is really what you want. It latches till it gets the next 12v signal.

I just thought the horn button would be novel.
