Almost a year ago I took my 2018 Camry to get the taillights rewired. They stopped working at night, fuses changed, bulbs and still nothing. I took it to my local Tuffys, spent almost $300 and not even a year later they have completed stopped working again. (Brake lights, turn signals and hazards work just not my taillights.) Shotty video I know but I took it to AutoZone and one of the guys came out and was looking at my wiring he noticed a ground was cut on the bottom of my trunk and what looks like to be previous wiring bunched together by the hinge of the trunk and new wiring running to where the sockets are. I do not believe these are my original sockets as the bulb that they said I needed is way too big but there's are the only sockets I have in the taillight section of my trunk. I kind of feel like an idiot as I really have no idea if this is normal and I have no idea what I'm looking for or at. I'm getting power to the sockets and plugs, the fuses are fine, in getting power to the fuses and they're still not coming on. Do I take it back to the original shop I got it done at for them to look at it? Any advice would be appreciated I'm still learning about cars and haven't gotten into electrical aspect yet so I'm stumped. 

Need some advice about rewiring I had some in my trunk.
