    Why this mod:
    So this write up is my method to combat tailgate theft. I already installed the hose clamp mod, but I didnt want to deal with the pop n lock because I didnt want another key and I did not want to pay for the electric model.

    What this mod does:
    This mod shoots barrel bolts through the frame of the tailgate and into the frame where the taillights reside. It basically creates locking pins on each side near the top of the tailgate. This is actuated with the car alarm.
    Anyway what you need is:

    What you need:
    2 typical car door lock actuators
    2 door lock bolts
    wire
    Drill
    t30 torx bit
    socket wrench


    STEPS:
    1. Start by opening up the tailgate and taking off the composite cover.

    2. You need to remove all the T30 bolts and then the cover should just lift off.
    [​IMG]

    3. Shot with the cover off
    [​IMG]

    4. Next you gotta remove the taillights for when we drill the holes unless you want to drill into your lights. Its just a few no. 10 bolts I believe, should be obvious.
    [​IMG]

    5. This is the barrel bolt that you need to install on each side, get a length that will work. The first ones I got were too short.
    [​IMG]

    6. The next steps kinda require some good old fashion intuition and measuring. Due to the variances in the locks used and positions you are on your own for drilling their location. What you need to do is drill as close to the top of the tailgate as possible to give yourself the strongest and most secure locking position.

    I eyeballed it all from inside the taillight space when the tailgate was shut. Then drilled through it. Here is a few shots. I ended up drilling through the lowest blue dot. When I got through the tail light portion and made a mark on the tailgate, I dropped the gate and continued drilling.

    Next you have to align the barrel bolt with the holes you drilled and then drill its mounting locations into the tailgate.

    7. Bolt up the barrel bolt

    8. Next it is time to get those actuators installed. These are the ones I used.
    [​IMG]

    When +12v and ground are applied to the wires in one configuration the actuator expands, when you flip the polarity, the actuator contracts. I wired up a few relays and connected them to my alarm door triggers. I used this diagram: (yours may vary based on alarm outputs) stolen from the12volt.com
    [​IMG]

    9. Align the actuators and the metal pins in line with the barrel bolt. They need to not bind.
    [​IMG]

    10. Test fit everything mounted on the top side, it makes things easier.
    [​IMG]

    11. I just bent the rods securely around the bolt tab, and its been working for me. Once it all works as required, mount on the underside of the tailgate so you can reinstall the composite cover
    [​IMG]

    12. Connect the wires and you should be good to go. There are a few places to run the wires out of your tailgate.
    [​IMG]

    I will provide more pictures if people want, or some videos next week if requested.

    Thanks and good luck.

    Post questions here since others may have the same ones.

    They are just the standard door lock actuators. DEI makes them as well as a ton of other companies. Any alarm shop will sell them. They are the ones used for installing keyless entry and older cars.

    They cost about $10-$20 a piece, depending on where you get them.

    Got mine at a local shop. He wanted $30 each and I laughed and said amazon had them for $8.99. He checked online and told me I could have them for $10 a piece. Any install shop will have plenty of these.

    Similar to the electronic pop n lock but about $80 cheaper.

    Looks far more secure than the pop n lock. Nice work and writeup.

    I like it! If my Dynolock ever dies I may convert to this and I have all the wiring all ready to go. This will provide a much more solid and secure locking method than the Dynolock, that simply interferes with the tailgate latch mechanism.

    One mod to this I would look into is to not use barrel bolts and instead get a piece of 1/4" aluminum or steel bar stock, center drill it, insert the actuator rod, then epoxy or weld them together. Attach this to the tailgate with an appropriately sized u-clamp to allow it to slide.

    Very good idea and design!
