Uncapped Plug Under Rear Bumper

[BMR]

Can anyone help ID this plug? I have a 22 and was underneath swapping plate bulbs to LED and noticed this plug unused and with no dust cap or anything. Toward drivers side. Thanks for the help!

Do you have bed lights?

Looks similar to one I saw on another thread.

Did you ever get an answer on this? I noticed that referenced thread indicated a six pin connecter rather than a four blade connector as in your picture.

Further it appears this four socket plug has but three contacts.

Probably a connection for an option your truck doesn't have. Or possibly a trailer camera.

Haven’t gotten an answer yet. Most suggestions have been of other plugs from what I’ve seen. Haven’t had a chance to put my circuit tester on it yet.
Also thought it was odd that it’s a 4 blade but missing a contact.

From what I have seen trailer aux camera is a different plug. Will post if I get it figured out.

Not much of an update but adding some info.

I don’t have propower onboard. It looks like someone else posted a pic of theirs and the connector I posted is plugged into a plug that splices right into the main loom. They have propower. Only guess for now is that it’s related to that option.


@Br549 do you have propower option?

Haha well damn now I’m more confused. The search continues.

Believe these plugs are for when you pull your tailgate. Your truck should have come with a bag of connectors, mine did. Looking at them they will either cover the connection to keep water out, complete a circuit, or provide a termination resistance for the vehicle CAN in order to keep that system happy.

I also have the open plug, but dont' have any sort of cap for it...seems like it should be covered up though just from it's look.

This cap fits. Finally hunted down the proper connector.

Not the same plug. This circuit doesn’t have anything to do with tailgate and none of the connectors in the bag are close.

I’ve come to learn it’s likely for pro power on board generator option.

Yes, I have the pro power on board - its not capped and uses that 4 pin. I have the 12 pin plug cap as well and that is for the tailgate and caps the connection later up in the harness.
