T56XL Help

So I have a T56XL in the car and the SAMCO reverse lockout box is hooked up and running fine. The issues I am having is a dead speedo
Codes:
P0720 OBDII A OSS Circuit
P0720 OBDII B OSS Circuit
P0722 OBDII A OSS Circuit No Signal

I had a shop do the wiring and I am running a tune that has not been updated for the T56.

Does anyone have any harness diagrams for the MT82/Harness so I can see what sensors are what on the harness and what wires to tap.

Has anyone succesfully done the swap avoiding the calibration box?

Thank you for your help

Mine will be going in nest month and you need to use the calibrator box because the signal from the sensor is different then the one from the MT82.

make sure you balance your clutch/fw/pp as one unit!
