Here's another thought. With the lock plate flipped upside-down, nestle the c-cam into its normal position against the lock plate in the same way the parts would be assembled in the column. Does any part of the c-cam brass contact ring touch the lock plate?
Hey, wanted to let you know that I FINALLY worked slowly and carefully looking at each part as they went into place. I placed the locking plate in place (not compressed with retaining clip) and pressed on it several times. No honk. I then moved on to securing the plate in place, No Honk. I put the steering wheel back together piece by piece checking for honk. Once all together, and battery was connected. No Honk!!!!! unless I pressed on horn button. So, the only thing different is the insulator on the c-cam. Something on the other c-cam must have been grounding it? I also changed out the relay, just in case. So, it seems like THAT is fixed.
Thank you so much for your time, expertise and pictures. Now, I have another issue that I will be posting in another forum about my brake light.
