    I reviewed the instructions which are pretty clear overall. I have two questions. 1) Which area gets the metal wire ties? The photos are a little bit unclear. I was looking for a diagram with all of the wire tie locations, but if there is one, I've missed. 2) What kind of sealant is that? Is it a RTV sealant or something specific to Toyota?

    The portion of the harness which is wrapped in a tinfoil-like thermal insulation (looks a little space-suit-ish) would be where you use the 4 or 5 metal zip ties. It's fairly obvious, there's a muffler nearby. You won't have much of any trouble figuring this out once you're underneath the truck.

    The sealant is to prevent corrosion I believe, it's a 3m product and you only need a very small dab of it. I bought the tube but I sort of wonder why I did. I think it might have been better to do one zip tie on the strut itself, cinched pretty tight then two zip ties securing the harness to that zip tie, one at the top, one at the bottom. That would have accomplished the same thing but without the metal clip and probably would have looked cleaner too, though this is all inside the skin so who really cares.

    Not sure how clear my description is but my thought was a larger zip tie from the red arrow point directly towards the bed/front of the truck then two zip ties securing the harness to that primary zip tie at the two sides of this metal piece. Looking at the photo more closely, though, you might need 2 of the longer zip ties, one for entry, one for exit, since the blue dashed line would follow the harness path. And I suspect you'd probably need longer zip ties than what was supplied, though purchasing long zip ties seems as easy or even easier than that 3M sealant and most likely fairly cheaper / more general purpose.

    I haven't found any use for the 3M sealant since using it for this.

    Also, and this appears to be only me, I swapped the ends of the tailgate connector and by doing so was able to click in the male plug on the white connector next to the camera male plug and have the tailgate side for both female plugs. This looks and feels like the way the harness was designed. I believe the manufacturer put the plugs on the wrong ends by mistake, hence the instructions to just zip tie it in place. The downside to zip tie-ing the male connector from the tailgate it is that you have to cut the zip tie to remove the tailgate, a very minor inconvenience but one I was willing to take the time to not have to deal with.

    For you guys that have installed it yourself, did you disconnect the battery? If you didn’t, did you have any issues with your power windows or sunroof like one poster suggests? Thanks.

    I did, for the installation of the T harness, then reconnected it once the T was in place because from there it's only 2 wires for the lock/unlock pulse which are designed to be disconnected when the tailgate is removed.

    Caribe Makaira has answered this question as well and suggests disconnecting the battery to avoid any trouble, even though that apparently is a bigger hassle on newer trucks where some things have to be reset?

    The instructions requiring disconnect, reconnect, move to lift, disconnect, and reconnect at the end are fairly ridiculous. If I were writing them, I'd do the T harness through the grommet first, move to lift if needed, secure the harness for the length of the vehicle, move off lift if lift used, install actuator and tailgate harness, connect to body harness, then disconnect battery, plug in T harness, reconnect battery, test, and close up tailgate skin and kick panel trim.

    I deleted the images to shorten the quote.

    DOH! For some reason I couldn't see that clearly on my copy of the instructions last night. Might have been the Scotch!


    That makes sense. What you did will work and I have plenty of longer wire tires of my own. I'll have to see how available that 3M stuff is and how much it costs.

    The rest seems pretty straight forward, if time consuming. I've done plenty of vehicle wiring before so should be all set.

    I received the shipping notice about an hour ago. Label has been created, but package has not actually shipped. That's how the USPS does it. Once a shipper creates the label, it's considered "shipped" even if the package isn't physically at the PO. No big deal.

    FTR, I didn't actually do the zip tie thing I am suggesting so I don't know how well it will work. I bought the sealant and followed the directions, however, I forgot to do the zip tie _after_ installing the metal clip because I didn't read that part too well before I closed up the tailgate skin.

    The sealant might be a good product for roof racks with OEM bolt holes and other spots where you want to try very hard to prevent corrosion on something which will get exposed to moisture. It's not overly expensive but I think the value proposition is pretty low for this specific application. A plastic snap-on bracket to secure the tailgate harness loom would have made some sense given the price point and the otherwise impeccable design.

    From looking at the instructions for this and a couple of Toyota/Lexus tow hitch installations, it appears that this is used not on the Tacoma for it's anti corrosion properties, but more as a glue to hold the clip in place. My guess is that this is something that Toyota shops have or should have lying around and it's convenient to use.

    I suspect that a good RTV sealant will do the same thing in this case since the harness is lnside the tailgate and not exposed as the tow hitches are.

    Just to be safe I followed the instructions and disconnected the battery. Probably was disconnected for a couple hours because I'm slow and methodical. I had read about how that might cause issues with the windows and sunroof losing their "auto" up/down/slide functions, but I had no problems when I was done and reconnected the battery; everything worked as it did before.

    I (and several others) had a bit of difficulty locating the proper grommet to feed through the cable from inside the truck cabin to underneath the truck. This post and the one it links show the proper grommet to use to route the cable. I initially pushed out the wrong grommet and it was a royal PITA to get back into place. Also, don't get any ideas about starting at the rear under the truck and working forward. I didn't do that, but I recall reading a post from someone that did... and when he got to the front the connectors on the cable WOULDN'T FIT through the grommet hole. :help: :annoyed: :help:

    Installed this a couple weekends ago on a 2019. Pretty straightforward. I didn't disconnect my battery but you probably should to be safe.

    Love the convenience. Not sure how I lived without it.

    I received the kit from BAM this morning. Pretty quick shipping. A quick check shows it the right one and complete.

    That Y in the cable with the connectors on it will definitely NOT go through the hole under the passenger seat. :D

    Other than that, it looks very straight forward.

    What I pln to do is run all of the cables then disconnect the battery, and then plug in the Y cable and reconnect the battery. That way, I'll have the least amount of time with the battery disconnected.

    I didn't disconnect battery. Don't really see where you would need to but it can't hurt either.

    Yes, the cable has to be fed down through the hole under the passenger seat. That Y cable assembly will NEVER fit through the hole. Well, it might, but you could well ruin the connectors in the process. Drop the cable down, wire tie it to the frame all the way back, then connect it to the lock. Then disconnect the battery, connect the Y cable connectors, reconnect the battery, test.

    Unfortunately, I don't have access to a lift any longer, so I'll be on a creeper underneath, routing the wires. :(

    At least it's not winter and at least it's a 2019. I used to have to work on ambulances during the winter and one of the things the lifts did was put the truck way up there so that the ice, snow, and salt had further to fall before they hit me in the face.

    Crews used to get pissed when we made them change into a spare for problems that would be solved fairly quickly. We learned to let the trucks sit in the warm garage for a few hours before putting them up on the lift.

    But, I digress. ;)

    Installed it a few weeks ago, super easy, works great. This should have been standard equipment on upper trim levels.

    I had the lock added when built truck thinking it would be OEM Toyota. Looks like the port used Pop-N-Lock on mine and spliced wires vs using Factory. Wasn't very thrilled about that as I would have installed myself.

    Installed mine today. Works great. Dealer wanted 6 hours at 135.00 per hour. I said no thanks and took my slow time so I didn’t mess up. Took about 3 hours from start to finish. I loosened my passenger seat to get to the rubber grommet which made running the cable a breeze. The worst part for me was all of the zip ties on the frame. This forum was very helpful. Could not have done it without printing the instructions. I did disconnect my battery just to be safe and didn’t lose any memory.
