Re: horn problem
I think you mite have the green and black wires at the relay reversed or your relay is shorting to the ground. the black wire should be next to the screw that holds the relay on the rad support. the cooper button is negative so it shouldn't have any voltage there.
another thing you can try is unplug the turn signal switch under the column and with a trouble light grounded touch the black wire going forward to wards the relay see if the horn honks from there.
