Installation

KTJO 4x4 Power Tailgate Lock Installation Tools - DIY Install Guide

Tools Required (not included):

Installation is very straightforward. It will likely take you longer to route the new wiring than to install the locking actuator.

Step 1. Assemble The Actuator

Initially, we need to undo our #30 Torx bolts holding the cover of the tailgate on. Then, set these off to the side with the tailgate cover.

Having a matching driver will make this go much faster!

Now it’s time to put the bracket onto the new actuator. This is done with two bolts, two nuts, one bracket, and the actuator itself.

After that is done, bolt the locking rod onto the black tip of the actuator. Grab your bolt and use a 9mm wrench or socket to tighten it. Do not over-tighten, however.

Step 2. Install Actuator Into Tailgate

First, we need to remove the two 10mm bolts that hold the OEM camera in place. (Don’t worry, the camera won’t move!)

Next, place the actuator and bolt it in securely with the 10mm bolts you just removed. Once that is done, you can now remove the #15 Torx screw from the OEM tailgate lock.

Once that is removed, gently lift up the black tab that the lock is sitting on.

The new locking rod of the actuator will slide over the black tab, and the OEM lock will slide back onto the tab.

Step 3. Route Wiring Harness

Now the not-as-fun part! We need to get the harness from the tailgate to the passenger side kick panel of the truck.

KTJO 4×4 provides replacement tailgate plastic grommets for a clean factory-looking install! Plug the green into green, blue to blue and you’re ready to start routing the harness.

I followed their install guide and removed the clip on the left side of the tailgate near the actuator to tape my wiring tightly to the factory harness. Having this loose also gives you a little more wiggle room when it comes to routing the wiring.

Tailgate Lock Wiring Harness Routing

Use your flathead screwdriver to push the clip in on the wiring harness. Once that first one is out, route your wiring like factory and carefully clip it back into place.

Next, you’ll need to repeat for the bedside. This one is a little more tricky due to the lack of room to work with. I ended up releasing the clip near the bedside grommet to give more play in the harness. This made it way easier to work with.

Once this harness is poking out of the tailgate, we need to get it over to the bedside and through the new grommet.

Place some electrical tape to keep the harnesses together when going to the grommets.

Step 4. Route Harness Under Truck

Next, we need to route the harness up the passenger side to the kick panel inside the cab.

This is super easy; just follow your existing harness, making sure to keep the wiring tight with zip ties along the way. You’ll see a large wiring harness going through a grommet into the cab. Pull this down and there is a small amount of tape that can be removed to slide your new wiring through.

Run the new wiring through the white factory clips to keep everything nice and neat. You can see where the wire loom is heading towards the right side.

Once you are at the kick panel, remove the plug pictured above. Next, plug in the KTJO 4×4 harness and connect the factory plug to the female end of the new harness.

You should be all set! Replace the kick panel back after getting all the wiring cleaned up.

Final Thoughts

3rd Gen Tacoma Tailgate Lock Review

My first impression of this kit was that everything was very well packaged and the instructions on their site were super clear. Everything was truly plug-and-play and I had no issues with installation.

The actuator itself is not too loud when you hit the lock button on your key fob, which is always a plus! Overall, this kit is well worth the price!

Thanks for this review. Can the tailgate still be unlocked with the key with this setup?
