Understanding relays... I'm a pre 40s guy.

Okay I read relays divert power... shut off items not used, diverting power to things being used actively, giving full power(ish). Not like creating resistance or power like a coil.


Did horn relays actually exists though on 36s? Pretty sure in 38 they did as the frame has holes for it. They included a fuse and lights.

Per the wiring diagrams, 1938 is the first year the cars started using a horn relay. The pickups and trucks did not use a relay until much later in time.
