If you know the answer to this please help? I have an 82-flatbed car hauler that the cab was shot on. I converted it to a 93 cab and tbi engine. The donor truck that the cab and engine came from was a 93 k1500 with a 5.7 and automatic transmission. everything on the swap went perfectly until I went to hook up the speedometer cable. Surprise, there is no speedometer cable on the 93. It used a pulse generator or speed sensor that screwed into the transfer case. Does anyone know of a Chevy that used an electric speedometer that I can put into my th400 to operate the speedometer? I am not sure but I think it also needs that signal to run the fuel injection correctly? I swear I have seen them before in an s10 or something? This may not be possable but I thought its worth a try and see if anyone has an idea and can help. I know this isn’t a hot rod, but it does haul them, lol greatly appreciate any ideas. Thank you

GM did use gear driven electronic speed sensors; late 80's to early 90's ('88-'92?) that will fit the T400 case.
Did you check the knowledge base?....

Actually I have been through the knowledge base and I use its helpful information for many things. Maybe I should edit and ask more specifically as to what vehicles they were used in?
