Too much focus on shape for an electrical question. Tried to talk "terminals" and their hook up, on that thing that is not a relay, with regard to year of truck. I agree on various shapes and their names, but that was not my concern in answering the posters question at first, then I was getting into Tims question about 53/54.
Anyway Ed, let us know if it eventually honks. At least you now know what it takes to make it work with TMI thrown in.(by me)
