Rear LED Tail light question

[Az4runnin]

I went to swap my passenger side LED tail light with my son to put on his Rig because some of his LED lights are going out. Now the turn signal and reverse light bulbs won't work at all. The LED lights work fine. I tried to put in new turn signal and reverse light bulbs but neither work. I am at a total loss as to what could've happened. Everything worked just fine before I took the tail light out. Won't work on my truck either. Any ideas?

Unplug the taillight for a sec and look at the connector. There's a couple little metal contacts that require you to insert and rotate the connector till they all line up, cause those power the secondary lights (signal/reverse).

If you just plug it in but don't rotate you only get the base taillight. The other possibility is LED bulbs w/ the polarity wrong, if the connector is fully lined up with those little contacts try flipping the bulbs 180.

I truly am losing my mind. My son came over. He bought a brand new LED tail light, and when I looked at his, I noticed the middle plug was plugged in. For some reason I undid mine and didn't plug that one back in. The other bulbs were in correctly. As soon as I did it, everything worked I truly am going crazy. I knew it had to be something really stupid, and well the stupid part was me. Thanks for the help [MENTION=686700]OopsIBrokeIt[/MENTION].
