I'm posting this to help others who may struggle to wire in a train horn
Here is how i wired it. Works great. I used a cheap Bad boy horn(with relay). Seems loud now (until i am near Knuckledeep, his is insane).
A couple things to point out.
I did not actually run the ground to the battery, i ran it to a ground distribution block.
I ran a heavy gauge 10 wire from battery to pin 30.
Wiring this way makes horn led only on when key is in on position. Horn only sounds when key is on.
Here is the LED Switch from amazon
