Just crawled underneath the truck checking everything out. Does anyone know what this plug is under the left rear door mounted on the frame?


This label is on both the front and rear driveshafts, interesting that if the drive shafts are dropped they are suppose to be scrapped.



The invoice indicated the truck was built on 07/22/16 and fuel tank was built on 07/27. Figure that one out.




New fuel filter and drain.

 

That plug looks like a plug for lighted/power running boards. Just a guess.

 

That's what I was going to say as well.

 

Not for power running boards guys. My truck has the same plug. Connection for the running boards actually comes through the cab.

 

Huh. Well then, I'm stumped.
