Question P2534 & P069e after X305 connector yanked out

Hello, hoping you can help me out.

2010 Enclave

Wife drove over a branch which pulled out the connector under the driver side seat (I believe it is X305). Before I noticed the connector dangling, she said the fuel gauge wasn't working and CEL came on. After finding, reconnecting it and reseting the CEL, fuel gauge works but CEL came back and I am now left with P2534 & P069e codes.

Inspecting the connector, pins, and wiring going to X305, it doesn't appear that there was any damage to them.

Doing a bit of research it appears that the P069e code is most likely a result of the P2534 code, so I started down the P2534 road.

Looking at the Fuel Pump Control Module, I was instructed to check Pin 15 (IGN 1 Pink Wire). I'm getting 0v with the ignition in the OFF and ON position, which appears to be the issue?! I checked the IGN relay and 10A Fuse under the hood and see ~11.5V there with the ignition ON. This wire doesn't appear to travel through X305, so I'm not sure where the correlation is or is a coincidence?

Question are:
- Am I heading down the right track here with this pink IGN wire?
- If so, what's the easiest way to trace it back to the engine bay?
- Is there a correlation between X305 and the IGN signal?

Any help would be greatly appreciated!!!

Well... I guess I will update this post to help someone out in the future.

The issue ended up being being the IGN signal wire between the rear connector X405 (by the spare tire) and the Fuel Pump module. There was an open in the circuit so I ran a new wire from this connector to the FPCM to resolve the issue. Not sure if having the X305 connector yanked out caused some type of stress on the wire harness or not but I hope this helps someone out.
