Why NO OEM trailer lighting harness for 2016+?

Im I missing something because I think there is an empty wiring plug under driver rear taillight that would make sense that a harness would plug in there for towing but maybe not. It is just frustrating if so because Id like to install OEM harness like may others and if truck is already wired for it, why not make it easy and correct. Maybe it is for something else. Attached is picture if someone can compare with OEM towing package.

 

Did it come with tow package.

 

How does a 3rd gen TRD trim not have a towing package?

 

No it did not. But was wondering based on high trim level and empty plug if truck is wired for it but just missing harness and connector.

 

If the money wasn't paid for the Tow package.

 

Good question. And my excited self didn't even notice it til I brought it home.

 

Thats how my Nissan was - connector, and a relay pack that were available from the dealer and just plugged in. Not an unreasonable expectation.

 

So far dealer has been no help and been looking on online OEM dealer websites and been unable to find it anywhere. Dealer said they stopped offering OEM harness at dealer after 2015 models

 

This says it's a probably not:

By the taillight? Most likely for the BSM sensor. What kind of bumper do you have?

 

Just regular chrome bumper

 

If it’s chrome, that’s almost certainly a connector for the blind spot sensor. If I remember correctly, chrome bumpers don’t have the blind spot system

 

Thank. This was helpful but unfortunately not the fix I was hoping for but not as bad as I thought

 

Yeah didn't consider that until you mentioned it, that would make sense.

 

BE1 is for Parking assist sonar, and cross traffic sensors. You have neither.

 

It was optional on the 16s and 17s, not sure about 18s. Standard on all TRD trims by 2019.

 

It's standard on all V6 motors after 2018.

I owned a 2016 Sport. Don't remember it being a separate option.

 

It was an option on my 17, thankfully the original owner paid for it.

 

I have a 2016 Sport and it was right on the sticker that I paid extra for the tow package.

 

Correct.

Here is the window sticker from my 17 OR. It was an option until 18 I think before becoming standard equipment on V6's.
