Horn wiring with blocked hollow shaft

[rich b]

Use a Jeep A302 brush (spring loaded contact) along with a copper water pipe coupling.

Decide on location, drill and elongate a small hole in the steering shaft, solder a wire on the coupling, "glue" the coupling on the shaft with JB Weld (but neatly), run the wire thru the hole up to the horn contact, drill a hole in the column tube, screw the Jeep brush onto the tube, run the wire to your horn or horn relay, and you should be operational.
