Tesla Model 3 Soft Close Door Installation Steps
1. Use a T45 screwdriver to remove the original car lock ring, replace our pad and place it under the original car lock ring. (It must be replaced before installing the electric suction lock, so as not to miss the replacement of the lock ring, resulting in jamming when closing the door and damage to the electric suction lock!) 
2. Use our matching screws to install our electric suction lock to the original car lock position. 
3. After installation, first use a screwdriver to lock the electric suction lock, and then pull the emergency rope to release it. Then close the door and observe whether the door can be closed. Adjust the position of the three screws of the electric suction lock or adjust the position of the body lock ring. 
4. Wiring diagram. Note that the wire should be routed along the original car wiring harness to prevent the wire from being caught when the glass moves up and down. The emergency cable is pulled out along the position of the original car and buckled to the original position of the original car trim. 
5. Electric suction test, first check whether the original car lock ring has a block. Without closing the door, use a screwdriver to lock the electric suction lock to the first level to see whether the electric suction lock works normally.

6. Install our motor module at the position where the damping teeth were removed. (Note that the motor module has a clip, you must press the door handle shell tightly when installing) 
7. Pay attention to align the LED lamp bead to the hole on the door handle shell when installing.

12. Special considerations for installing glass on the front side door: ①adjust the position of the back frame slider to the middle of the door, so as to avoid hitting the rear shell of the auto present door handle during glass installation; ②the glass installation near the lock block requires two gaskets, because the original car screw is too long, it may hit the back shell of the auto present door handle otherwise.
