    Update: SOLD to local buyer.

    Anyone still looking for a harness made by old-red for the turn signal & puddle lamp?

    I got one for my 2020 TRD Pro, but never installed it. Decided to not install anymore because I'm not sure how much longer I'm going to keep the vehicle and I don’t want to spend the extra time and money on the upgrade.

    See attached photo.

    I'll sell it for $50 shipped.

    I can attest this harness works great! I used it in my install and the conversion to blinker/puddle light mirrors looks and works like it came this way from the factory.

    Anyone with a 21 or newer get the puddle lights to work? I got Tanner‘s harness, went back-and-forth over the phone testing all connections and terminals with a volt meter. Turn signals work great but it seems, at least Tanner thinks, that Toyota coded it out on the 2021 and possibly newer model years.

    I used Tanners harness on my ‘21 TRD Pro. Blinkers and puddle lights work great. Puddle lights illuminate when I approach the truck with the key fob on my person. My truck was built fist week of July 2021.

    It's a long list...
    That's my working theory at this point. Whether or not that is correct requires more data. I have noticed more and more features are now "programmed" vs physical circuitry on the refresh that was introduced for the 20MY.

    @Bobafett you and I checked everything for continuity, grounds, etc. and we couldn't get the puddles to light up. No 12V output from the main body ECU. What was the build date on your 2021?

    I should also add that @Old Red is an absolute stand up guy. He bent over backwards trying to help me out and even refunded my purchase (which I wasn’t happy about due to the amount of work he put in lol) My build date is Jan. 2021

    I’m sorry it didn’t work out for you. I don’t understand why it worked on my truck that was built 5 or so months later and not on yours.

    These side mirrors with turn signals and puddle lamps come standard with the ORP. For thousands of dollars more you would think they would be included with the PRO trim. Very strange.

    Especially when TRD Pros delivered to Canada are equipped with them. That’s why I don’t think Toyota would significantly change the wiring between them. It does seem like the harness that goes from the front kick panel area and into the door is what’s changed.

    Well, that makes it double-strange. Why Canada and not U.S. deliveries ?? Ultimately, sounds like a question only Toyota could answer.

    So we have a Jan'21 and Jul'21 build date. One worked, the other did not. @Bobafett is your standard key or push button?

    You would be surprised. Toyota does weird stuff for no apparent reason when they package trims. Why not dual zone climate control on the premium trims in the U.S? Canada has that standard on all 4Runners, there are no base trims for them. Why created 20 variations of a wiring harness, why not just 1. It would be more "Kaizen". You would be correct, they change the peripheral harnesses more than the main dash/body.

    The wiring inside the doors is actually different depending on year, trim, and from what I can tell maybe production date. That said, the individual circuits did not change from 20-22MY, only additional wiring was added for touch handles, etc. The main dash should be the same for that specific trim level (i.e. SR5 & SR5 premium share the same dash harness 14-19MY) When I was doing my research initially this is what I found based on year, and at looking at the post 2020 refresh.

    2014-19MY

    3X Door harness types

    Specific Trim levels shared dash harnesses, but peripheral wiring was trim dependent

    A- Base model/TRD Pro, no premium mirrors

    B- Premium model, upgraded mirrors

    C- Limited, Touch handles, memory seat, upgraded mirrors

    Now for 2020-21MY they continued that layout from 14-19MY, except when they did an ignition changeover mid model year from standard key on base trims to standard push button start.

    4X Door harness types

    D- Base model, no premium mirrors, regular key (Early 21 only; not sure of changeover date)

    E- Base model/TRD Pro, no premium mirrors, Touch handles

    F- Premium trim, upgraded mirrors, touch handles

    G- Limited (Premium + memory seats)

    2022MY

    5X Door harness types

    H- Base model, touch handles, Regular mirrors

    I- TRD Pro, touch handles, regular mirrors, BSM, MTM

    J- Premium Trim, touch handles, upgraded mirrors, BSM

    K- Premium Trim, touch handles, upgraded mirrors, BSM, Panoramic monitor

    L- Limited, touch handles, upgraded mirrors, BSM, Panoramic monitor, memory seats

    This is what is leading me to believe it might be trim programmed in the Body ECU for 2021 because even with physical circuitry present and hooked up, there is no function. Again this is theory at this point.

    Good old physical key, no push button.

    Where is everyone getting the turn signal mirrors? I am guessing I can swap them and just slap on the painted mirror cap?

    I have a 2021 trd pro

    Nice! I have the same vehicle. Give or take how much did this whole mod cost you? Trying to device if I wanna go ahead with it.

    Need to check with Red on his current price for his harness. But the most expensive part are the side mirrors. They are about $200 each from a dealer new. I’m sure you can find used ones online.

    Awesome! Do you happen to have the part numbers for the side mirrors? Thanks in advance

    I can confirm these are the correct part numbers.
