The horn wire could burn before the FL opened.
My assumption, & comments, are in the belief that the OP intends to power the horn relay direct from the bat [+] terminal or the alt terminal. Either way, the most effective protection is an inline fuse [ or cct breaker ] in the feed wire to the horn relay.

That's the thing Geoff, you have valid points, but I'm advising the OP on exactly how the Chevrolet division wired these cars. Based on his earlier pictures, he purchased a factory style horn relay. The relay also doubles as the power distribution point in these cars--the horn relay has a direct connection to the alternator and battery power at all times with no dedicated fuse with its sole purpose to protect the horn circuitry.

If he were to install a fuse just to protect the horn relay, then he could no longer use the side bussbar connections on the relay for his main charging and feed lines--he would have to come up with another terminal arrangement, then connect the fuse assembly between this new main splice point and the horn relay bussbar itself.

Re: 1964 Malibu horn relay

Not sure if this will get read. Iím needing a little help with the horn relay on my 64 as well. I have all the manuals, shop and assembly. I have a color coded wiring diagram as well. New wire harness is from lectric limited. The problem I am having is I donít know where to attach the black wire coming out of the harness near the horn relay. Diagram shows it attach on the left/driver side. Is it grounded using the attachment bolt for the horn relay? Thanks for any help/pictures.
