Hi, the vehicle speed sensor connects directly to
pin 28 of the engine ECU, (passenger side inner wing area UK) if you look at the connector from the wire side it looks like a squashed "T" the top row of the "T" from left to right are 1>19 middle row 20>37 so 28 is in the middle row it connects to the VSS on pin 3 you will get a voltage of 0>12v fluctuating with road speed.
