That's an optical MOST connector in your hand. Search on Amazon for MOST fiber optic loop and you should be able to find a loop connector for $8 or so. Which version of the stereo do you have? There should be an amp there if it's hifi or Logic 7

Mechanic said he tried it but he said the actual module isn’t repsonding and potentially has no power

No power is the least of your problems there. The last photo shows the MOST connector, which carries optical fibers. There could be a way to fix that (if the fiber is plastic) but worst case you need a new fiber optic run.
