Tools needed for the installation
Removal of necessary trim pieces
Open the tailgate and remove the tailgate trim panel. It is sufficient to just open the right side, but
removing the whole trim panel will make work easier. If any clips break, get some new ones.
Here you see the removed trim piece with all the clips reinstalled.

5
Remove the trim pieces on the top and lower part of the inside of the trunk. For the top piece you first
need to remove 2 clips. To remove these clips, you need to pop the inner part with a screwdriver, then you
can remove them by hand.
The lower part can just be pulled up. Than pull the carpet on the left and right sides inboard, and remove
the cable from the trunk flood lights.

6
Open the rubber tube which is going from the right side of the trunk, to the liftgate on the bottom and
top.
Also open the tie wraps which is holding the rubber tube in place. You can open these tie wraps with a
very small screwdriver. In this way they can be used again. If they break just cut them off and install
new tie wraps after the installation of the power lift.

7
Open the frunk and remove the cover. Also remove the air inlet. This one is hold in place by 4 plastic
clips.
Remove the left doorsill. To do this you first must remove the cover which is on the left side of the
dashboard, then the cover which is between the doorsill and A-pillar. (in this piece of plastic you can
install the extra switch)

8
After you removed these panels you can see a clip, from which you need to pop the center first. Than
you can pull the doorsill out.
Remove the 2 taillights. On the inside release the connector from the taillight. Release the plastic screw
on top of the taillight and two 8mm nuts on the inside. The outside of the taillight has 2 clips, so you
need to pull the taillight aft to release those.

9
Installation and running the wiring harnesses.
The computer (part 7) will be placed in the right part of the trunk behind the carpet and below the
woofer (if installed). So, all the wiring must go to this area.
Power cable.
Open the 10 mm screw on the + of the battery. Be careful not to touch any metal parts with the tools,
since this will give a shortcut. Insert here the fuse holder (part 14) and fasten the screw again. It is
recommended to remove the fuse from the holder and replace it until the full installation is complete.
From the right foot well pull the carpet down. There you will see a rubber grommet with 2 orange (high
voltage) cables.
In this grommet, with a sharp small knife, make an incision. BE VERY CAREFULL NOT TO TOUCH THE
HIGH VOLTAGE WIRING.
Use a piece of sturdy electrical wire to pull the + of the power cable (part 9) through this hole, so it
enters the frunk area. Use this wire to pull the + connector of the power cable through. Connect the
connector in the plug of the fuse holder.

10
From the right foot well, hide the cable behind the trim panels, in order to reach the right side of the
trunk. A good place to hide the cable is tugging it under the right door sills.
From the back seat remove the side pillow. It can be pulled forward and up to remove it. From here
you can see more wiring going to the trunk area. Bring the purple connector of the power cable to the
right-aft side of the trunk.
On this power cable there is a ground connection. Connect this to the 10 mm bolt behind the right tail
light.
Can bus wiring.
From the left footwell, find the most forward plug and search for the blue and purple wire, which are
above each other. (check if this is still valid for your car, because Tesla tends to update there wiring)

11
Take the can bus wire (part 8), with the 2 wiretaps already installed, and connect them. The red-white
(H) wire must be connected to the blue wire. And the red-yellow (L) wire must be connected to the
purple wire.
Now route this cable under the left doorsills to the rear. In this wire there is a yellow wire sticking out.
This one is not used. It is easy to remove the left pillow of the backseat to reach the trunk area. Then
also route this cable to the right side of the trunk area.
If you want to install the extra button to close the trunk from the driver area, run the wire (part 11)
along the same routing to the trunk area.
Installations of the liftgate harness.
Now the fun begins. We need to run cables from the trunk area, via the rubber tube to the liftgate.
The best way is to use your sturdy electrical wire and bent it . The bent must be pushed from the top all
the way through the rubber tube to the trunk. Use soapy water to help guiding the wire.

12
When you managed to get the wire in the trunk area, get these 2 cables from the liftgate wiring
harness (part 10)
Tape all wires well together so the package is as thin as possible. In this case there is less chance of
damaging wires and connectors. Now pull, with the electrical wire, the harness through the tube, to
the liftgate. Use soapy water and someone to help you guide the cable. Be careful that the harness
does not grab any wires in the tubing, since this will damage the existing wiring of the car. Once you
succeeded to get the harness in the liftgate, you did the most challenging part. Congratulations!
In the liftgate reinstall the wires from the harness in the plugs again.
Use this picture as a reference for the colors. It is important not to mix up the colors. Once the wire
connectors clicked in place, reinstall the yellow and white locking pieces on the plugs.

13
Disconnect the existing connector from the liftgate latch and connect the Y-connectors to the lock
control. Connect the Y-Connectors to the new harness.
The purple lead from the new harness will be connected with a wiretap to the green wire of the
existing switch to open the trunk.
or
The lower side of the liftgate wiring harness must also be led to the right trunk area.

14
Installation of the new electric struts
To install the new struts, it is best to do it with 2 people, one for holding the liftgate and another to
remove the old and reinstall the new struts. It is also good to remove both the old struts before
installing new struts, since the length is a little difference. To remove the struts, use a screwdriver to
release the clips. Than the struts cab be removed from the ball joints.
The news struts can be clicked in place easily, without releasing the clips. Be careful to mount the struts
with the cables on the bottom, and the strut with the long cable left, and with the short cable on the
right.
To route the cables into the car, it is best to drill holes behind the taillights. The hole should be 18 to 20
millimeters. The best position is on the inside of the hole for the connector of the taillight and in
between the 2 screws. After drilling the hole, use some paint or other rust protection material to
protect the cut edge of the metal to prevent rusting. Use the rubber grommet to make the hole
watertight.
Then lead these wires to the right trunk area.

15
Replacing the catch hook to the electric catch hook
With a torx 45 bit release the existing hook and replace it by the motorized version (part 1). Put the new
hook in the middle position, it must be adjusted later.
In the bracket where you installed the ground wire, drill a 3 mm hole. This is a good place to install the
motor of the motorized catching hook with 1 screw.

16
The cable between the motor and catching hook must be put behind the carpet. Release 2 clips to do so.
Installation of buttons
Drill a hole in the indicated spot (marked in red) to install the trunk close button. Use the drill bit. Connect
the button and reinstall the trim panel.
If you use the extra button near the driver, we recommend this position

17
Now all the wires can be plugged in the computer. Also, the buzzer must be plugged in. After this is done
be sure there is nothing which can obstruct the closing of the trunk. Also plug in the closing button in the
liftgate and the one in the driver area (if used). Just put the computer in the trunk with all wiring away
so it can become stucked.
Now install the fuse in the frunk. You should hear a beep, and on the computer, there will be a red
flashing led. This is normal. Press the close button, the trunk should close. Open the trunk again. Adjust
the catching hook if needed. Try all functions, display, app, buttons and key fob (if you have this). When
everything works fine, it is time to clean things up; take care that all wiring is tucked away neatly, in such
a way that it can’t get damaged over time. Take car of sharp edges. The computer can be placed using
the pieces of 3M tape behind the righthand taillight on the bottom. Be careful it doesn’t rattle. Use tie
wraps to clean things up. Reinstall all the parts from the car which you removed.

18
Installation of foot sensor:
To install the footsensor the bumper needs to be removed.
To do this behind the rear wheels on both sides removed 3 clips.
Than under the car remove ten 10mm bolts (2 behind flaps). Here are pictured the 5 on 1 side.
Two 10mm bolts which are located under the tail lights they need to be removed. Also on the forward
side on the inside of the bumper there is a small torx screw hidden behind the trim. Remove these two
as well. Then remove the bumper with 2 people. Start with pulling the forward sides outward.

19
The bumper is hold in position with clips. When lowering the bumper you will see a plug for the bumper
sensor. If you will not pull the bumper away from the car, leave this one in.
Install the kicksensor on the inside of the bumper. Clean the area where the sensor will be placed, and
stick it with double sided tape to the bottom of the bumper. Route the cable to the inside of the car via
the right ventilation opening.
Now connect the ground to the same position of the powerlift. Connect the yellow + cable with the
fuse to the power cable of the powerlift. Install the green sensor cable to the purple cable of lift gate
harness.
Install everything back together.
