How to get GM TECH2 CANdi module to work

355The Candi Module should not plugged into your Tech2 unless you’re working on a later car ..generally 2005 plus. Olders car from 96 should NOT have the Candi Module attached.

OBD I only has 1 ground, so 12 pin adapter connects signal and chassis ground to the Auto diagnostic tool Tech 2 cable.

OBD II has chassis and signal ground and they are connected in the cars wiring.

How I was trying to get GM TECH2 CANdi module to work:
Nothing on CANdi end of cable.

Boot screen not showing CANdi present, diagnostics for CANdi says it isn’t seen.

The weird looking screen is because I have not removed the protective plastic yet.
