Re: 1962 C10 Horn Installation
The black wire starts at the relay and continues up to the large connector on the firewall. It should continue thru the harness until it meets the turnsignal bundle going into the column.
Power will run from the horn relay up into the column and when the button is pressed it grounds the black wire to the internal metal of the steering shaft.
I'm most familar with 64-66, but it should be similar.
