Find the right diagram and the plug pin-out for the dash...

Or do it the easy way and run 2 wires to the plug on the gearbox speedo sender and tap into/intercept the speed signal, 3 wires +(maybe 5v or 12v, can't remember which) negative and signal...should be easy spot which by wire colour, or use multimeter.

Its not an analog voltage signal, its a digital pulse....ie you can't measure it with a multimeter ! (might be able to with an led, or oscilloscope )
