You will need to add an actuator to the drivers door there is no actuator there only a switch when the actuator locks that door all doors will lock.

i should also add you wiill need two relays to make it work .

On both the relays pin 87 and pin 86 will get 12 volts positive ,pin 87A will get ground on both relays, and pin 85 will go to your lock wire, and on the other relay pin 85 will go to your unlock wire from the alarm or keyless entry module.Now pin 30 on both relays will go to your actuator. You will need to make sure your alarm is putting out a negative pulse to triger these relays. good luck . posted_image

dont forget to fuse the constant twelve volt input to pin 87 and 86 a 10 amp will be fine even a 7.5 will be good.

just use the aftermarket actuator and leave the passenger door alone it will lock from the drivers side .
