Installation
Step 1 - Run the ECU harness
On the ECU, you will need to connect the power source, the ground and the CANBUS. For the power and ground, route the two wires to the frunk through the firewall. Connect the power to the 12v battery (For 2022+ car, connect the power to the jump post). Connect the ground to car chassis.
Firewall location, circled in Yellow. It should be on the right side of the MCU for LHD car
For the CANBUS connector, connect it on the right side of the car, behind the kick panel (Refer to Step 3 Front Door, but on the right side). There is an idle blue connector to plug the CANBUS connector.

Step 2 - Disassemble the doors
Follow the guide below to remove door panel and window.
There will be one wire going to each door. Run the wire through the door grommet into the door.
Front Door
For the front door, the wiring is pretty straight forward to run.
Release the upper clip that attaches the middle A-Pillar trim to the vehicle, and then pull the trim upwards to remove it from the vehicle.
Simply Pull
Release the topmost clip on the lower A-pillar trim.
Use a flathead screwdriver to pry on the channel on the clip to release.
Pull the rearmost part of the lower A-pillar trim upward to release the clips and tabs, and then pull the entire trim rearward to remove the trim from the vehicle.
Now you can fish the wire through the conduit to the front door.
Rear Door
For the rear door, we recommend removing B pillar trims for easier wiring.
Remove the 2nd row lower seat cushion. You can simply pull up the seat.
Release the portion of the rear door seal that overlaps the lower c-pillar trim.
Release the clips (x5) that attach the lower c-pillar trim to the vehicle, and then remove the trim from the vehicle. Tip: To later aid with installation, note how the lower c-pillar trim mates with the trunk side trim.
The rear clip might be difficult to release, sometimes jiggle the piece out can help. Don't pull too hard or it might break the tab.
Release the clips that attach the upper B-pillar trim to the B-pillar.
Note Release the bottom clips first, and then release the clips at the top of the trim. When installing it back, insert the top of the upper B-pillar trim under the headliner to align the clips, and then press the bottom to fully seat the lower portion of the trim. Ensure the seal correctly overlaps the trim.
Simply pull it out
Release the lower portion of the front door seal.
Release the tabs (x3) that attach the front door harness guide to the vehicle, and then release the harness guide datum from the lower B-Pillar trim (Simply raise it).
Simply use your finger to press on the release, it will release the tab.
Release the clips that attach the lower B-pillar trim to the body, and remove the trim from the vehicle. Some car might have an extra philip screws on the top of the trim, remove it if it's there.
For the rear clip, just use a flathead screwdriver to release it out from the channel
Release grommet connector. Pry at both the top and then the bottom of rear door harness grommet while pulling away from B-pillar to release door harness
You can disconnect the connector after releasing both tabs. If you find it difficult to disconnect, try to use your hand to press on the two tab while you disconnect.
Remove rubber grommet from rear door assembly
Insert the terminals into both sides of the OEM connector. Make sure the color match each other on the male and female side. Two of the wires use the big terminal and 4 of the wires use the small terminals.
On both side of the connector, pry this the long rectangular piece, and then you can insert the terminals. Use the 4 idle small holes. Relock after inserting. Make sure you match the color on both sides. On the door side, it's easier if you fish the wire to the connector through the short grommet before inserting pins.
Insert the terminals. Make sure you insert it all the way in. Use a needle to help to push the terminal in if necessary. If the cover cannot be lay flat after inserting the terminal, that means some terminals are not fully inserted.
Step 4 - Remove the OEM Door Handle
Disconnect the hall sensor connector from the handle
Remove the plugs on the doors so you can access the screw nuts on the handle.
Front door
Rear Door
There are 3 10mm nuts holding the handle. Remove them then you can take out the handle
Step 5 - Replace the Handle
Remove the 2 T-20 screws holding the hall sensor and transfer it to the new handle.
Unscrew using T-20 screws, this is a CN sensor (China made) and no spacer is needed to be added behind.
Transfer the hall sensor to the replacement handle and reassemble it onto the door. Inspect the hall sensor; if it has a "CN" mark printed on it, there's no need to place a washer behind the sensor. If it doesn't have a "CN" mark, it's a Mexico hall sensor, and you should place a spacer behind it. Afterward, retighten the screw.
Reconnect the OEM connector to the handle and connect the wire that runs into the door panel. On the ECU side, ensure the connector for the corresponding door is plugged in.
Step 6 - Test the handle
Reconnect the OEM connector to the handle and connect the wire that runs into the door panel. On the ECU side, ensure the connector for the corresponding door is plugged in.
Test the handle for the following functions:
Press on the tip of the handle; the handle should pop out.
Pull on the handle; it should unlatch the lock, and then the handle should retract.
Ensure the handle moves smoothly when it pops out and retracts. If it doesn't, try adjusting the handle's position.
Before you close the door, if the window is installed back, make sure you connect the puddle light before testing, otherwise the windows trim can be damaged as the window will not go gown upon closing.
