Trailer AAG Module Not Reading

[LuvMyX5TowVehicle]

The OEM Trailer harness and Module should be a simple install but I cannot get the X5 to see the AAG module. I have codemycar doing the coding and they say there is no power or connection to the module. Plugs A2, A3, and A4 go into the Control Module and can't plug in wrong. A5 goes to the CanBus plug pulled from the harness by the fusebox and I double checked none of the pins fell out or back. And A7-A12 I double-checked are all in the fuse box in the correct pins.

My brake controller plugged into A13 tested out great on the road - of course there are no trailer lights without the AAG reading so i didn't leave the neighborhood.

Can I get some suggestions on troubleshooting - I'm not getting anywhere reinspecting pins and fuses.
