Nice job on the '53 Ron, only wish I could down load the pix from Webshots for my reference file. The picture shows the location just fine.
I'll check through the catalogs and see what they have listed.
I doubt if I ever showed the truck that any one would notice that it had a relay added.
Yes, the horn is hot all the time and the button just completes the ground on my '50. The horn on the '53 is grounded and the relay is feeding it B+ when it's energized. Looks pretty simple and a lot safer setup also.
Thanks
