    I originally posted this in the What Have You Done Today thread, but thought it might see more action here.

    I wired up my tailgate to open automatically when I hit the unlock button on my key fob three times within 4 seconds. It is glorious, cool and borderline useless all at the same time.

    Took one of these ($11): https://www.amazon.com/gp/product/B0002J22BO/ref=oh_aui_search_asin_title?ie=UTF8&psc=1, two of these ($33.50): https://www.amazon.com/gp/product/B0009SWLE6/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1, some wire, an in-line fuse and a standard Bosch relay that I had laying around. Since I have a Backflip MX4 that adds a bit of friction to the top of the tailgate, I also ended up needing one of these $6.00 door poppers: https://www.amazon.com/Baosity-Stai...=door+popper&qid=1555095721&s=gateway&sr=8-41 Total of $52 invested.

    My truck came with the Toyota/ Pop-A-Lock tailgate lock dealer installed, so I just had to add two wires going to the tailgate, add the actuators to the handle, and wire it up to the passenger side footwell where the tailgate lock was already wired into. I downloaded the directions from an old post on a different Tundra forum years ago as a pdf. FOR INSTRUCTIONS SEE POST #12 BELOW.

    I had to read it three of four times, but yeah, I think you hit the nail on the head....

    I did this on my 2011 Tundra a few years ago and remember a guy getting out of a brand new King Ranch in the grocery store parking lot as I walked up to load groceries see me do it... the look of disgust on his face when I told him that it was standard on all Tundras was worth every second it took me to do it!!!

    That’s awesome, strong work. I’ll take the pdf...jrharvey02@gmail.com

    Oh, and could you wire me up something that closes my wife’s mouth when I hit the unlock button 4 times? TIA.

    If one had a choice between the unlock button 4 times doing this ^^^ or making your c*ck bigger.........I do believe that you really do have a decision to make!!!!

    I'm definitely interested on how to install. I added a diy pop and lock. Do I need a second actuator to move the tailgate handle? I assume that's what it takes. They are cheap enough that I would definitely pick one up and do this mod.

    Takes two additional actuators for the auto-tailgate drop. I think the pop-a-lock uses one.

    I've e-mailed 12 or 14 members the pdf instructions and think I sent one to everyone that requested them. I sent out about 10 about 5 minutes ago on Monday (4/15) morning. If I missed someone, please send another message.

    Hey guys!...new member here, just brought my 2020 Platinum, and want to add both the lock and auto open feature...never did anything like this before, I’m trying to look up the Bosch relay but there’s a million of them, which one do I need???...I’m somewhat handy so I know I could do this all myself but never used anything quite like this...and what gauge wiring should I use to run from tailgate to cab, 16 or 18?...thanks in advance!

    I bought these relays from Amazon, although any "Bosch Style 12V relays" should work just fine, and yes, there are a million of them. I've used 18 gauge wire from the cab to the tailgate every time I've done these runs. If you don't have any on hand, you might also want some crimp-on terminals, a wire stripper/ crimper, T-taps or Posi-taps (18 gauge to match the wire), an in-line fuse holder or three. And maybe some 1/4" or 3/8" wire loom to protect the wires on the run through firewall (or body gasket) and under the truck and bed, and then up into the tailgate next to the wires going to the rear camera. And maybe a voltage meter to ensure you don't royally screw the pooch and short out the head unit- to be avoided at all costs.

    Ok awesome, thanks for the help man!...yea that’s the part I’m a little nervous about, what wire goes where...seems like a lot of wiring involved and I don’t wanna screw it up!...I have in lines, taps, and all other stuff needed, so I should be good, just hopefully make the right connections...hahaha

    This is really awesome! Great detail on the write-up and the pictures are really helpful!

    I was about to click Buy now on all of the things listed then I thought about it....

    My ARE topper won't let the tailgate open unless the glass door is open.. hashtag-dangit Maybe I'll look into an option where I press the unlock button 4 times to open the glass (it's on gas shocks), wait 4 seconds, and press unlock 4 times again.

    Or I'll continue to be jealous of those who have done this.

    Thank you for this @ncorry. I downloaded your instructions and purchased all the parts I was just about to do this when I realized I have no idea how to install the two Pistol type door actuators. The instructions do not mention how you mounted these or have pictures that show them installed. Can you please provide additional details on how you attached these to the rods that release the tailgate and where are they mounted inside the tailgate? Lastly, can you still open the tailgate manually or do you have to use the remote going forward when this is installed?

    FYI, like you, I already have the locking/unlocking functionality so I just need to do the steps to add auto open. Attached is a photo of how my locking/unlocking actuator is installed.

    EDIT: Nevermind. I am an idiot. I just realized the top part of page 4 showed this.

    Did you get it figured out? Yes, you can still manually open tailgate.

    Also, if your pop & lock is already installed, you only need 2 wires to the cab, right? For the opening actuators only?

    Thank you for this. Looking forward to some quality covid19 quarantine time this weekend. I've found several diy projects I'd like to test out. Between naps.
