I spent half an hour checking old threads but don't find my answer.

I guess the horn wiring and relay on my 50 Dodge are different than a P-15 or D-24 and it is on the firewall not in front of the radiator. I hope someone with a relay similar to mine can offer some help. I am in the middle of rewiring my car and am hooking wires up to the relay. The horns have not worked since I bought my car and I suspect it was not wired correctly. (I should have tested the horns direct to battery but failed to do so - yet).

Across the top of the relay are two screw terminals and one bullet terminal. On the lower right is another terminal. When I got the car the wires were hooked up as follows:

1. top left - wire to horns and the ground wire that goes up the steering column.

2. Top middle - wire to coil, wire to ignition switch and wire to turn signal flasher

3. Top right bullet terminal - no wire

4. Bottom right - to starter solenoid

I have attached an illustration.

Questions:

Looking at the wiring diagram for my car it does not appear that the ground wire should go to the same terminal as the wire to the horns or does it?

Nothing was connected to the the bullet terminal on the top right - does anyone know what it is for?

The 1950 plymouth wiring diagram shows 4 wires as follows

H terminal #10 green to horns

B terminal #10 green to starter solenoid

I terminal #14 red to ignition coil

G terminal #16 black to horn button.

Sounds like you might be missing either the piece that goes from the bottom of the steering column to the relay or the entire wire up the column. My p15 has a bullet connection at the bottom of the column but the 4 terminals on the relay are all the same none are bullets.

Ok reread your post you have the wire up the column but if 50 dodge follows 50 plymouth yours is in the wrong spot.

I suspect the wire that goes to the horn ring should go to the bullet terminal since all the others agree with your 50 Plymouth arrangement. I will try that.
