My moulding that fits under my steering wheel was broken, so I got another one from a junkyard. When I removed my moulding, I saw these three connections - two attached to the moulding, and one just hanging around, so to speak. Nothing was plugged into them.

Curiously, on the truck at the junkyard those same connections were similarly not attached to anything.

What are they? Thanks!

 

The blue on is a diagnostic connector.

 

yup the blue one is for the rear ABS, the other one could be for an option that your truck does not have.
