I make my own up using an original wiring loom as a sample. I can't make one for what those guys are getting for them. There are some differences between the connectors on the factory relay from 55/56 to 57 up but everything else should be the same. The early ones use ring connectors and the later ones use spade connectors.
The ebay guys are probably buying them from old trucks for $25 and selling them for $95.
