Does the wiring harness flip up over the top of the radiator somewhere? I couldn't quite get to the wires, therefore couldn't see where they went when unplugged.

I'll try to help you, but not sure what you mean.
The stock horn gets fed by a connector (a plastic male piece that holds wires together). The connector goes into the stock horn socket (female).
After you pull the connector out of that socket, it simply hangs there (not flipping over anything).
Then you take that connector and plug into the stebel relay socket (female).
The logic here is simple - when you hit the horn button, you trigger the stebel relay.
So a low current (stock horn button) now controls a high current (Stebel).
If you think about the way it works logically, it should come clear to you what connects to what.
