Hi. Was told that a VN speed sensor will also work on a M21 gearbox. am currently running VB 308 with M21 gear box in a hot rod. Due to behind dash restrictions I want to run an electric Speedo but require a hall effect sensor on the gearbox. I believe the thread sizes are the same on the M21 and the T5 boxes but would you be able to wire it so it sends a signal through the wiring to the electric Speedo

just need 3 wire loom with the power and earth to it and signal to the speedo, also if ur using aftermarket speedo may have to see if the speedo has a voltage on the signal wire or not, if it dosnt then use a 10k resistor from the speed sensor power wire to the signal wire so the sensor has a voltage to pull down
