What is the black plug for on this harness? It’s on the right c-pillar.

 

Purely a guess, but i would say its for the power sliding back glass...

 

I saw that when I had the back panel behind the seat off. It’s down low in the middle of the the back of the back seat below the window.

 

If you find the missing accessory you'll know what that plug is for.

 

Doesn't appear in my electrical schematics. My guess is inflatable rear seat belts.

 

Lol @16IngotFX4 very true! @52merc i didn’t know there was such a thing especially in 2017 model. Maybe I’ll be able to repurpose somehow.

Is there any power to it?

 

Well I figured it out and will be working on its use this weekend. Its for the roof wiring harness that has the stuff for AHBC/LA/Rain sensor. I am putting this on the truck this weekend and hooking up. Already got a new windshield and have the harness and rain sensor. Just have to drop the headliner. Should be fun!
