The headlight switch is a standard auto parts place item, even for a 40+ 
year old Ford. The relay is available there also, or you can buy a 
pre-wired harness from someplace like www.autodynamic.com that simply 
‘plugs in’.

You can get the relay info by typing
headlight relays
into your browser search engine.
