Dont know how I can find this out so hoping someone can help.
The electronic speedo drive out of BE3 gearbox has 3 prongs for the connector.
Live
Earth
Signal.
question is which is which?
My car never had this drive before so my haynes wont cover it, even if it did I wouldnt have the wires to check the numbers off against.
Anyone a genius and know how to work it out, or better still anyone have a loom knocking about for a car with one of these drives that can check the wire numbers leading to the pins and let me know Would be helpful if they could also tell me what loom it is so I can get hold of wiring diagrams to find out.
Many thanks

the road speed sensor is usually found on the injection/ignition wiring diagram. these hall effect sensors are usually pin 1-ignition live,pin 2-earth,pin 3-signal wire. to double check the code printed on the ignition live wire should start with the letter C,the code on the earth wire should start with the letter M,which would leave the signal wire that code usually starts with either 13 or 12.
