That conector has extra wires because the body harness A is used for TWO diff kits , one for radio display and one for a mirror display.
That's why you don't use the "yellow" wire , for the mirror kit the Yellow wire also connects to the BCM @ a diff connector C-7 socket 6 if my memory is correct .
That's why I suggested to ensure @ the radio harness connector / Body harness A connector to ensure the three wires leaving the connectors ( going to the radio ) are the same on both sides of that connection.
Ensure the connector you populated has the following
Cavity A = Grey/Blue
Cavity D = Grey/Orange
Cavity E = Bare shield wire
The other wires do not matter , hell for a radio install you could cut them off !
Equally important is to ensure the factory built Radio harness B was populated properly @ manufacturing by making sure the wire colors are @ the same locations from the connector you populated above to the factory Radio Harness B , continuing to the radio , make sure :
31 = Grey / Blue
32 = Grey / Orange
33 = bare shield wire
Good luck Sir , Hope this helps !
Fantastic ! You have grid lines right ?OK, it works now. I had 31, 32, 33 in the slots above those in the 52 connector. Thought they were all the way at the bottom right, but they were one row up. Camera works now.
Considering the diagram in instructions showing where 31, 32, 33 should be installed are wrong, I rate this at a 10 out of 10 difficulty. It simply will not work when installing per the instructions. That step wasted about 3 hours of my time. Otherwise, the install was very simple. If it were not for this forum, I'd be stuck calling who knows how many people at FCA trying to figure this out. Thanks for everyone posting up here and especially RLK and Mpgrimm2 !!!

You do not need the flash , your truck is already flashed for some reason , something with your wireing , I wish I could help more now , but I just shot a doe 15 MIN AGO with my PSE BABY !I have read through this thread and can not find the answer to my unique situation. I have a 2013 express with the RA1 radio. I upgraded to the RA2 radio which was pulled from a family members truck that currently had a backup camera installed. I installed the RA2 radio and backup camera kit 82214240. All of the settings for the backup camera are currently on the RA2 radio. I currently get a blue screen when placing the gear in reverse. NOTE: I have not had the dealer flash my truck for backup camera. My question is, Do I still need to get the flash from the dealer in order for the camera to work? Or is it that my wiring is not correct?
