1965 F800 wiring diagram needed

[clarrance]

Does anyone have a wiring diagram for the engine/firewall area for a 65 F800. My neighbor has a relay that is broken and he doesn't know what it's for. And the truck doesn't want to start. To me it looks like a horn relay, it only has 3 prongs on it, but the center prong is broken off.

I agree looks like its a horn relay not much else it could be back then. Dont have any 65 diagrams but maybe 67 is close enough should be anyhow. try this link. http://www.fordification.com/tech/schematics_h.htm

Is he getting spark? if not he might try just running a jumper wire from the battery to the coil. Could be a broken wire from the ignition switch, or a bad switch thats the issue.
