Tail/Brake wiring harness on a 2015

So my camper shell's center brake light apparently has never been connected. I want to rectify that but I don't want to use those damn quick-connects that use insulation-displacing connectors on the existing wires.

When we did the trailer wiring on my wife's Jeep, the kit came with a T-connector that took signal by having one unplug the harness from the back of the tail light, plug the t-connector into the harness, then plug the t-connector into the light housing. Wires off the t-connector then ran to the trailer lighting controller. I've been trying to find a similar arrangement for the Frontier but so far I'm not having a lot of luck.

It appears that there are two different wiring harness configurations for the D40. The early one uses a harness attached directly to the bulb sockets, with a single large connector for all lamps. This later 2015 Nissan Frontier uses discreet connectors for each bulb, so one for reverse, one for turns, and one for brake/tail. The first two are two-wire, the third is three-wire.

One of the things making my search difficult is that I could not find any clear pictures of the wiring harness connector or the bulb socket connector, so I decided to take some and post 'em for others that may be in a similar position.

One more picture, the harness itself.

Replying to my-self Ooh Ooh Oh-oh...

Looks like Nissan calls the grey female connector 11020W9A03-GR, and it might be the same connector used for the ignition coils. I found other part numbers J-48817-110 and J-48817-125, apparently Bosch numbers. The family is "HS" for what that's worth. Still trying find out what the male connector is called and any part numbers.

More I look at it I think it's the 125, not the 110.
It looks like Toyota uses the same 11020 socket and did before Nissan did, so I speculate that Nissan decided to simplify their parts-list by using the same bulb-socket part as Toyota used.

Someone else needed to extend a socket and didn't want to cut up the wiring either, they managed to eventually track down a Toyota 90980-11607 plug that was used on an Asian-market Hilux. 90980-11607 is unfortunately entirely bare, and has to be populated with pins and seals.

So if I were to build-out a t-connector of my own for the one side to activate the center brake light I would need the following:

1- Toyota 90980-11020- 3 pin female plug

3- Sumitomo TS/SL Female terminals CONN-11856

1- Toyota 90980-11607 3-pin male plug

3-Sumitomo TS/SL Male terminals CONN-10069

6- Sumitomo HM/MT/TS wire seals CONN-00145

Plus whatever I use to come off of one of the connectors to connect to the two pins of the center brake light.

Contacted my local Toyota dealer today, their parts department confirmed that part number 90980-11607 is not domestically available. Looks like it'll be hitting the ebays to get one unless I can find a better choice. I would still like to know the actual manufacturer's part number prior to it being Toyota-ized since I expect it comes from another supplier like Bosch or Sumitomo.

EDIT: looks like 90980-12697 and 82821-50550 might be crosses for 90980-11607, but having trouble finding pictures.
