I've got 'em wired to pins 71 and 72 are x1 connector on the ecu.
71 Is the vss signal high and 72 low Is the vss signal.
Pin 57 Is What I am using for vss output (yellow / black wire).
On my harness, only the terminal 71 which is wirring.
I don't understand what I must wire my E38 PCM to have speedo on my dash board.
Can you help me?
Pin 71 doesn't show to be for VSS. It has TOS, whatever that is. Go through the schematics again and find the pin for VSS high.
