Ed,
Sorry you missed the point for my posting. While I am happy to know that your dad found a substitute for the relay, that knowledge does not tell me what he used, where to get it, or how to connect it. The site I posted provides that information. Whether or not you choose to install it within an original relay box is irrelevant. I happen to like it that way but that was not why I posted the site. I just thought someone would like to know where to buy a substitute, what part number to use, and how to wire it up.
