Default Speedo on dash, VSS wiring question

Hello,

I bought a chassis, engine and transmission of a 2007 Cadillac Escalade that burned.
L92 is equipped with a 6L80 in a 4WD.

I want to install on the frame a FORD F1 pick-up body.

I changed the wiring:

I tune the PCM with HPT and you can see the engine starts correctly:

I found post which say:

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?

Thank's

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.

What is TOS?
There aren't VSS high on the schematics.
The car is a cadilac escalade 2007 with L92 engine, E38 PCM, 6L80 and 4wd.
