What is this for

Forgive me if discussed before but I pulled the right tail lamp and find this. Looks like a grease fitting but nothing is attached

I’m guessing the tail light snaps onto that post.

At least the tail light version on the raptor does not, the light housing does not appear to get close to that

It's a zirk fitting for pumping in new blinker fluid.

I'd guess it's a grease fitting for the tailgate motor or something related.

Nothing attaches to it on the back

It’s for tailgate assist.

Why pull the taillamp?

Stevdug · Sep 22, 2022

What does it do for tailgate assist, I have it but nothing is attached. Was adding a bed extender needed to remove the light
