Ok, well I'm trying to figure out how to wire things here... A couple of things I'm thinking about are A) Wiring the compressor lead to one of the toggle switches, and B) Wiring the air horn into the truck horn with a switch that can turn the system on and off (so I can just hit my truck horn w/o the air horn when I want, or hit the steering wheel horn and have the air horns go off).
Another thing I have thought about is whether I can use my air horn with my alarm, ie, when the truck horn goes off with the stock alarm it will also activate my air horn. Not sure if the alarm horn is a different relay than the steering wheel activation relay? In this case, would I just need to wire the air horn on/off to a lead that does not turn off with the ignition and leave it on when I leave the truck?
Keep in mind that I am not going to be wiring this myself and am not good or knowledgeable with these things, only want to find out so I know what options are available when I get this installed and can pass the info on to the installer. I have found that going into things like this with knowledge of how things are done is always the way to go.
