Re: 1936 120 Horn Button Wire Feed thru steering column

I suspect it will be the same route they used with the 35 120 as shown in this illustration from the 120 introductory manual. That method appears to be similar to all models thru 54. There is an insulated contact plate sitting on the top of the steering shaft with a wire running straight down the tube, thru the box and out the end. A length of wire approx 6 inches long sticks out . There should be a bullet connector on the end to join another wire in the loom which goes on to the horn relay.
Note that the contact plate and wire does have to come off or out to remove the steering wheel. Some unsolder or cut the wire at the plate and push the wire down the tube a bit with a reconnect when the wheel is replaced. Others pull the entire wire out. I prefer pulling the wire but use whichever method works for you.
Be advised if you pull the wire completely out there is a narrow constriction at the bottom the wire has to feed thru. That makes it difficult to get the wire down and thru if you try to replace from the top. If you feed a length of stiff wire up the shaft starting from the bottom and then attach the horn wire and pull it back down it usually goes fairly easily. Lay the wires end to end and use tape to join them. Keep the attachment to the horn wire very smooth and compact and don't use a lot of force when pulling the wire or the tape can separate. The narrow tube wire passes thru at the bottom is not much larger in diameter than the bullet connector.
