rider, my boat don't rock, well anchored by 3 original GM factory BW-OD trannys,

did you look at that link? it has a companion
about wiring here - never heard'em called anything else, and the shop manual doesn't give the OD a name
maybe the actual OD unit part aren't T85N's, but that's what we've been callin the trannys here
for years - don't know if Ford used BW too
