I've pretty much read all the "air horn" threads available and understood most of it, except for one thing. The12Volt and others said you should connnect terminal 87 to a fused 12+ source which I'm assuming means running wiring with an inline fuse directly from the (+) of battery. Correct?
However, I could like a cleaner install with as few wires under the hood as possible and if possible tap a (+) source (maybe cigarette lighter?) which is already fused from underneath the dash. Which wire should I tap and is this setup safe?
Also, I was told my Clifford Matrix 1 cannot be connected to both the siren and horn since one is contant and the other is pulse. Is this correct? If this is the case then how would I wire the horn, air horn (above), and siren to go off when the alarm is triggered?
Thanks for your help.
You'll get a cleaner install by doing all your wiring under the hood, unless you are installing the horns inside your vehicle. Also there is a good chance your lighter circuit couldn't handle the load from the horn.
To make the horn pulse off the constant siren output wire it up using a relay with the parking light circuit acting as a pulsed trigger. One other thing I like to do with air horns is to use an additional relay so that the horn will only be triggered if the dome light comes on. This is a good way to distinguish a false alarm from an actual breakin.... it will also keep the neighbors happy.
