Extra connectors behind knee panel

[Jas]

I was installing the Obd bypass and saw these two just hanging around. Anyone know what these are for?

I have a 2022 3500 Limited with, what I thought was, everything. But seeing these 2 I’m thinking I may be missing something.

I've got the open gray connector attached to the knee panel as well and I have the Aux switches. Not sure what it's for. I didn't see the blue one when I was in there looking for the upfitter connections.

Yes it’s got me wondering. I have the factory aux and wires in the engine bay.

Those are the two connectors for the VSIM. They have nothing to do with the AUX switches.

my aux switch harness is plugged into the gray connector for the pass through for the aux switchs.

Nope, not THAT particular gray connector. The one in question is a female socket connector. The aux pass through connectors under the dash are male spade connectors.

Thanks! I will keep those tucked away.

I have noticed the gray connector on my ‘22, now I’ll have to go look for the blue one.
