camera shows open line error

[TMINTN]

2014 silverado new body style wt quad cab

 

I upgraded to io6 from io4 with the 8 inch screen. I added a back up camera. I had WAMS update my hmi.

 

Now I have a black screen with directional lines and the ECU says I have an open line error.  error codes B101E, B127B, U15F0-00  from the module

 

could the truck not been fully wired? The dealer was no help on that, just error codes. I have a 6 pin plug in the rear mod and the grey and yellow striped wire and white wire is there, but i do not know where they end up. I lose them in my search.

 

I have had issues finding a schematic to help, the wrong year, the wrong model is easy to find. I need a back up camera. please.

Adding this for people searching in the future however 99.9% of the time a vehicle built without a rear camera will NOT have all of the wiring from the camera back to the HMI.
