Tail light question

[Tucknroll]

Anyone know what these are for? My left side is really dim and reverse light comes on but barely when lights are on. It's a brand new taillight harness. Thanks

The tab I mean

I would say it would be used to connect a ground wire to. Grounds are the most common problem there is on our old Mopars. Be sure to really clean all of your grounds on the car and use plenty of dielectric grease on all connectors.

Ok. So I should connect them all together and ground it I'm guessing

You might even have to add a ground wire. It is a bad idea relying on the body to ground everything especially after you’ve painted the entire car inside out!

Try to ground just the one side an see what effect it has.
