Need help with wiring of Train Horns

[The Car Stereo Company]

so you will probably want to wire the compressor to a switch or to ignition. (as long as it has a psi cut off) that will allow the tank to fill and then automatically shut off the compressor.

You want to wire it to an ignition switch with a 15 amp fuse. You want the compressor to run only when the truck is running.

So couldn't I add the compressor power to aux 4 as well, and that would be the ignition switch?

 

[Yukon Joe]

If you use a relay, yes. Aux 4 is a 10 amp fuse, so without the relay, it would be too much draw.

So aux 4 will power both relays which will activate your system.

I wired mine like this:
upfitter to 85 or 86, doesn't matter. also powers to pressure switch
the other (85 or 86) to ground.
Built a breakout harness to plug in horn harness
power from horn relay to 30
OEM horn to 87b
Train horn solenoid to 87.

The connector for the horn side is WPT-1193
The connector for the body harness is WPT-1051
the body of the horn WPT-1193 was just a hair too long to lock so I sanded it down slightly.

You also need a 5 pin relay, I see in your pic you have a 4 pin.

Thank you, I ordered a five pin. Hoping to get it done this weekend.
