    Can someone help identify these two connectors for a 2015 Tundra 4x4, they plugin to the 4WD control module and interface to the truck, 4wd selector switch, transfer case and ADD.

    I need to buy them to help with some wiring I'm working on

    You need to buy them, as they are not in your truck anymore?

    Are you trying to add the full 4x4 system? Or?

    Yes, I'm converting my truck to 4WD. Once I get these connectors, I'll create a custom harness to connect the 2WD/4WD HI/LOW switch on the dash and drive the ADD and transfer case.

    I would rather bypass the 4WD ECU and just have toggles switches for the ADD and 4HI/LO.

    Then I would not have any feedback on whether everything engaged. If I wire everything in then I get status lights on the dash.

    I’d trust my senses more than a light. It’s pretty easy to hear and feel when 4x4 engages but to each their own.

    Can use LEDs.
    I've messed around a bunch with the 4WD ECU. That thing is very finicky.

    The 4WD ECU has to be connected to the CAN BUS so that it can communicate with a whole bunch of other systems. If it can't talk properly to any one of those systems OR is actually getting a message that the other system has a fault, then it's going to prevent you from shifting to/from 4wd

    Then plan B will be diy switches/lights but I'm going to try factory first. It's not for the looks as I've moved the 2008 Limited interior into my 2015 SR truck and switched from front bench (with the middle seat) to center console... a little cutting and I made it fit.

    Correct, I do plan to wire into the CAN bus, otherwise no dash lights.

    I'll be using the 2015 4WD Control Module... I have everything in the 2008 (bought a limited 2008 4WD with a bad frame for parts) but I compared schematics and the 2015 wiring is lot simpler so I'm buying the parts needed for the 2015 setup but cannot identify these connectors.

    I went to a local dealer last night and they only sell the entire dash harness at $2,700+, no thanks!
