When I picked up my '59 the horn worked. After the regulator/generator/ammeter issue, the horn was not working. We got back on the road and I figured I'd fix it once back home. THe horn works when jumping the brown wire at the relay to ground so I figured maybe something came unplugged when the one tech was under the dash fixing the fuel gauge. I looked yesterday, and the brown wire from the column is unplugged. Where would the connector be to tie in the horn ground to the relay?
