SHOCKING! What did I do wrong?
For those playing along at home... 1967 Convertible
So, If I am driving the car with my arm on the window sill touching the metal parts of the "door," and I press the horn button...
I get a shock/jolt of electricity.
What did I hook up wrong?

It may be no ground at your steering coupling rag joint. The OEM joint had wire mesh inside it to complete the ground. Most replacement rag joints lack the wire mesh inside and require a wire lead strap.

I think
We need some more testing!
Maybe after about 20 more shocks, we will be able to figure out what wire got pinched in the steering column horn hookup and is shorting 122V to the metal button at a certain position when the wheel is turned! I would take the horn assembly button apart, disconnect the 12V and start doing continuity tests!

Definitely a grounding issue with the column. (rag joint area). The horn relay has a coil to activate it that will discharge and cause the shock. You can put a jumper between the two sides of the rag joint connectors to test the theory.

Current always takes the path of least resistance to ground.
If sometimes, that is through your arm to the door, it means the ground to the horn circuit is a weak/intermittent connection.

Service replacements and later models (C3?) had the molded in mesh.
Original steering coupling ground strap:

How loud do you yellwhen you hit the horn?
Maybe you don't have to fix the horn!

Greg, did you get the spring issue straighten out? This looks like an easy fix. How is the car doing?

Ok for funny
Lets assume you have walked across some carpeting building up a static charge before jumping into your Corvette, therefore maybe we should hook multimeter leads to you to see if that might be the culprit.

My 65 did the very same thing. I didn't care, just chose not to blow the horn. Anyway, I pulled the engine to rebuild and paint - reinstalled and grounded the engine and exhaust according to the manual. No more shocking when blowing the horn.
