No reverse lights

Just had my front diff replaced last week and noiticed last night that the reverse lights are not working. The relay under the hood is fine, bulbs are fine now what? Is there a fuse not listed in the fuse panel? I don't think there is need to disconnect anything under the truck to replace the front diff or is there? Help!

1. Somewhere the harness has grounded on the reverse wire. It could have been nicked I imagine.

or

2. The signal when you put it into reverse from the shifter is not working and not completing the circuit.

Just curious if you put it in reverse and connected a tester to your trailer wiring harness what would happen...

Upon further investigation the trailer lights and rear sonar are not working as well. Thinking it must be something to do with tha BCM update that was done last month........back to the dealership again. Last month it was front diff which took 3 weeks to come in. The two things that are important to me and need to be reliable on this vehicle have let me down which makes me concerned when traveling to far away destinations
Just venting
