My train horn set up

[Rammstein1224]

Hey guy thought id throw this up here and see if you guys notice any problems with my set up

I might add a relay to the air solenoid, depending on the draw of it. Don't forget the horn switch is on the ground side of the circuit.


EDIT: I may be wrong with the horn being on the ground side. I had a wiring diagram for the horn, but I can't find it.

I just found out on another thread that its 300 mils and he said it should be fine with just the horn wiring

I always put a switch between the pressure switch and compressor . That way I can control the compressor as well

I wired my compressor to an ignition on power source, that way it only runs with switch on or truck running. Don't want a leak to develop and it kill your battery.

I prefer to have a switch on the compressor too, because the pressure switch will and can fail at some point. That way you have another way to turn it off and can run it only when you want or need too. I ran all my switches through my upfitters.

Key on power is an idea. I would put it on a switch though. The compressors I've been looking at pull 20-40 amps. I'd rather not have another 40 amp load starting the truck in the middle of winter. And as others have said, if there is an air leak/ bad pressure switch, you could turn it off so you don't drain the batteries or burn out the compressor.


I was also planning on using another air solenoid on the lowest port on the tank so you can "dump" the air to drain the water. Better than being under the truck and letting an 8+ gallon tank dump 150 PSI+ of air out.

i like the key on idea where would i tap into that circut?

Look at my album for my tank and compressor and horn mount pics

I've got move tapped into the fuse box to one of the fuses. Cant remember which one as it's been a while, but haven't had any problems. Some might say not to do it this way but I see no problems with it. Year and half with no problems.
