Train horn wiring. Question
Got a train horn and compressor, want to wire it up to a toggle switch inside vehicle and a separate key fob and and relay
http://www.ebay.com/itm/like/400764241561?lpid=82&chn=ps
Just wondering how to exactly wire it up. Want to go to From train horn/comp to toggle switch one to turn compressor on and one for the horns. also into the wireless receiver (just for horn, on key not compressor)
Any idea's or thoughts thanks!

What train horn do you have? You should have a separate power and ground for the compressor. Just wire the switch in line with the power or the ground on your compressor.
As for the horn itself, there should be a valve or a "horn" button somewhere. You just have to wire up the contact relay normal. But there will be a signal wire coming from it. Basically a wire that is grounded at rest but sends a power when you hit the remote button. Perhaps even power at rest and ground when you hit the button. Whichever, make sure it's connected to the horn button correctly. It's a little complicated without knowing which polarity activates the valve and what polarity the relay box sends when activated.
