speed sensor question

[S.O.B.B.]

Dave w thanks for clearing that up.I read so many different things trying to figure how I'd make my set up work.I had opposite were I could no longer run the speedo cable due to trans having a pulse ring and sensor.I didn't know the 427 would and accept 2k pulse.that's interesting because in my plan to go back to auto trans I thought about converting the cable drive on the auto to electronic so I didn't have to mess with the speedo issue again.but at least now I know I could go back to cable if I had to and get the signal to the ecm.good info.thanks
