How to get CANdi module to work

I think that is the perfect excuse for me to buy an LT4 equipped Corvette.

Here is what I found tonight.

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

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

How I was trying to get CANdi module to work:

Nothing on CANdi end of cable.

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

Here I connected OBD I adapter to end of CANdi cable:

OBD I adapter connected.

CANdi module shows up at boot screen.

Green LED flashes about once every second.

Diagnostic screens for CANdi now present. Hit ENTER, 4, 7 to get to this screen.

POST Results.

Self Test Results.

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