    Perhaps the harness from the 2020 models may be an option. (?)

    We don’t believe so, you can currently populate the pins in the ECU that the 2020s will use, however they will not function. The ECU will need to be re programmed for that to work, which of course would reprogram your keys as well, at this point in time the only way we see to accomplish this will be via tapping the drivers door wires. If you can source the correct female harness that would mate with the male connector you are purchasing (you would then need twice as many connectors and pins as you currently need) you could make a plug in harness between the drivers door handle and wiring with wires that will lead to the passenger door, however the function would be the same as tapping the drivers door wiring.

    As Victory says above, just to reiterate
    Based on my work with the 4wd ECU...
    The fact that the 2020 gets multiple handles natively will likely do nothing for us...
    I will almost guarantee security ECU didnt change for 2020. To make the passenger pins active, a change is made by Toyota to the year/vehicle model specific ECU, which then tells the 4wd ECU, Security ECU, etc which options to turn off and on.

    For example, the same 4wd ECU is installed in 2wd (with rear locker) and 4wd vehicles (with and without locker). Main ECU tells that 4wd ECU what vehicle it is installed in, and what options to turn off and on (like locker anytime vs 4lo only).

    You can install the new 2020 Security ECU in your (2016-2019) truck, and I will
    almost guarantee that it will revert to only the drivers door pins being active.

    (Not 100% positive, as I have not been able to find the 2020 ECU PN yet, but it is almost guaranteed based on how the other ECUs work)

    Note, only way around this that i know of would likely be modifying the main ECU software, (such as Ovtune) to change the operation modes of the security ECU, or 4wd ECU, and good luck with that.

    Just wanted to verify this was the right part.

    I was looking around and saw one of the sites mention this.

    We want the part number that would be for the DRIVERS SIDE even though we will be installing on the passenger side.

    Do you mean that's what they're asking or
    Is that because they don't make a smart handle for the passenger side?
    Would that mean the sensor is on the bottom? I'm sure I'm overthinking this.

    Just order the part number you have listed in the first post and I should be good.

    If you look at your driver's door handle, it actually has the lock sensor lines on the top and bottom. Toyota probably did this so they could be reversed.

    The handles have sensors top and bottom and are the same when flipped over. They only make smart handles or not smart handles. The drivers door smart handle will install without issue on the passenger side.

    My dumb ass just learned there is a sensor on the bottom. Wow, all this time I thought it was on the top only. Now I wonder if my Corolla had the same. Thanks!

    Stuff that my wife thinks I don't need.
    I need to get off my duff and get this in. I've had the parts for weeks.

    If you have the @MESO puddle lights in the mirrors this passenger side smart door handle mod will light them up when approaching from the passenger side as well which is a nice bonus!
