rear camra wire loose?

2015 Chevy Silverado 1500, High Country 6.2

 

Last time my friend used a tractor to load something onto my truck bed and the bucket got caught on my tail gate cable and broke it which caused the tailgate to hung on just one side cable and the rear camra wire. It must have pulled the camra wire loose or disconnect from the housing inside the truck bed? How do I go about fixing this issue. When put on reverse, the screen says "rear camra service" Thanks in advance!

I'd take it as no one has this issue before?
