I think you'd need to use the vacuum to run a compressor, and then you'd need to store the compressed air so your horn would work when vacuum is low.

It's true. I really don't do anything but browse the Internet looking for trouble... | | | | | Joined: Feb 2004 Posts: 29,869 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,869 | Go to a salvage yard, and get the air shock compressor off an old Cadillac Fleetwood. (Late 70's to mid-80's) It's already got a pressure-control switch built in, and you can use a small Freon tank as a reservoir. The control valve and air tubing for the horn can be had at any truck parts store, and you're in business!
