Horn Relay what dose it do 1946--1972 trucks
well I've seen this a few times and the battery can really couse that problem but in 1950--1966 chevy trucks the Horn Relay controls all the power in the truck i will show a picture of it the one power wire that gose to the Horn Relay Gives power to the Fuse panle that's where you get your parking lights head lights and dash power even before you turn the Key switch when the truck is not running even thow the Key must me on to work the wiper motor and some Radios the Key switch hets it power from the purple wire that come off the starter. If you look most truck will have a wire running for the battiey post to the drivers side of the truck and it gose into the fuse panle.Now i say buy a extra Horn Relay switch cus if your stuck out in the middle of no where you pretty stuck .You can NIGG rig it and hook them aall to gather but chances are them smaller wattage wires will not like the 12 Volts and then you have a fire

That is the same setup that is used on the 65-66 Impalas and probably other year Chevys as well. If you look at it closely the relay is just used for a termination point as all three large wires are in contact at all times. The relay does not control the power for the cab. The wires just happen to bolt to the terminal that feeds the horn relay, but they are not controlled by the relay.
