Hello. I have a Spectra astro siren hooked up to a apx6500 and hln1241d dek. Dek Pinout 17 is hooked up to a rocker switch which activates the siren. Anyone know which pinout activates the air horn? Thanks

The DEK has all the buttons programmed..siren ,yelp,wail,hi/low, airhorn etc. When I hit the airhorn button on the dek it activates it. The airhorn button on the dek does not correlate to specific default pinout? Only reason trying find out is that the dek is mounted in the glove box and I can't reach the buttons when I'm driving. I would like to hook it up to a momentary switch

That specific pinout would be programmed in the software. There are VIP PINs on the back of the DEK. One sounds like it is programmed to turn your siren on. You would have to program one for horn ring, and set horn ring to the airhorn tone in the radio software. Those inputs are assigned separately from the buttons.

One more quick question. Could I tap a grounded wire to each individual pinout to see if it eventually activates the airhorn or would I be risking messing up something.
