Odo speed signal wire.

[Terminator]

My laptop with all my MKIV tech papers on it has suffered the blue screen of death.

 

Question - Is the pink speed signal wire to the odo the first point of contact of the speed sensor signal wire, or does it come from another componant bewteen the speed sensor on the box and the odo in the dash?

The speed sensor's first output is transmitted along the blue-red wire that splits after the sensor. One branch feeds in next to the pink wire on the Odo and the other goes to the speedo. The Odo buffers and re-transmits the speed signal out through the pink wire, which is next to the blue-red input wire.

 

The pink buffered output signal feeds the PPS, Cruise, Active Spoiler and then winds its way to the main ECU.

 

If you want a speed signal that comes from source tap into the blue-red wire. If you are getting a code 42 fault you need to add a bridge connection from the incoming blue-red Odo wire to the pink output wire and cut the pink wire's connection to the Odo plug.
