!975 Horn Help
I'm trying to get the horns to work on my 75. I started at the horns themselves. Tested good with a car battery, after cleaning the ground area. I found the horn relay up high above the fuse box. I then jumped the red wire and green wire to the horns. They worked from there. I then tested continuity from the relay black wire to the steering column harness, the third blk wire from the right. That was good. Then from that same point on the harness, I tested continuity, to the horn spring loaded button on the hub assembly. Not good. My question is, where does the black horn ground wire end, in the steering column? Will I need to pull the hub, or can I just lower the steering column? There are no wires present at the horn eyelet. I tried for continuity at the lower contact assembly as well with no luck. I put in a new relay as well just to rule that out, I hope. Thanks, Tom

You will need an Allen set screw to go into the center of you tele-shaft so it will stay put when you suppress the lock plate.
