You just jogged my memory.
Now I remember where I've seen that before.
In the 1954 Chevrolet Accessories Booklet. page 53
And the 47-54 Factory Assembly Manual. Section 11 sheet 30 RPO 430 & 431
This
Diagram shows one horn.
This
Diagram shows one horn but I have to rotate my screen to read it.
I thought there was a 1954 Chevrolet Accessories Booklet on
chevy.oldcarmanualproject.com I assume all horns have a relay no matter if there are one or two horns.
Another thing I just learned.
There is a matched horn accessory 986397
And a add on high note horn accessory 986893 or RPO 430 & 431 to the already existing low note horn.
