Hi. What you have to do is connect some inverter relays (not common and if they are mini relay better) directly to the driver side motor to use it as a slave. Each relay is armed as follows. terminal 30 to the driver side closing motor cable (cut the cable at the door stop) 87a to the other end of the original cut wire. 87 to positive. 85 to positive. 86 to the gray wire (Green) of the alarm. In other words, the 2 relays are assembled the same with the difference that one of them uses the gray wire at terminal 86 and the other the green wire. If you are not sure of doing so, I recommend you send it to a socialist to install it because if you connect the inverted cables you can burn the engine or worse the CSI of the car. Regards
