Replaced tail light bulbs driver side tail led light doesn’t work

Hello, I recently replaced my passenger tail light unit after smashing it on a trail. I ended up replacing the turning and reverse light bulbs on both sides and now my driver side tail light isn’t getting any power.
I checked and all my fuses are ok. I plugged the drivers brake unit into the right side and it lights up no problem.
The drivers side only lights up when I press on the brakes.
Any suggestions as to what could be cutting power like this?

 

Has to be a broken wire then, they get their power from the same source.

 

Yep… ripped the splice while taking my bumper off the other day. All good now thanks
