the power door locks don't have a button. you have to pull the driver or passenger manual door lock lever to actuate the power lock. will I need a door lock module to get a keyless entry system to work with my car?
There is only a switch and no motor on the drivers door. The power lock is only on the passenger door so you will need a second motor.

I installed an alpine car alarm which opens and close both my driver and passenger door locks on a 1989 240sx, no motor needed. You can get the wire diagram on bulldogsecurity.com
I have been told you need an actuator on the driver side. Not sure why. There is a motor on the passenger side so why not just hook up to passenger side. The rest is vacuum controlled. I guess the keyless entry need a electronic acuator rather than vacuum actuator.actuator=relay.
There are two large green wires(one with black stripe) that go to door lock which mitchel's wiring diagram show coming from door lock timer. I assume they power the door lock. I took a pic of a brown connector that I don't really understand. An orange/black and a black wire go in and a red and a black wire go out. I assume the black and red wires are going to the door lock motor. If I disconnect brown connector , doors lock or unlock by themselves. Brown connector is found in door kick panel next to door lock motor. The Mitchel diagram only shows the orange/black wire going from door lock timer to switch than ground. I'm guessing that the switch is on the motor and is actuated when the door lever is moved manually. I don't know what vacuum actuation is. I think everything is controlled by door lock timer.
I bought a bulldog keyless entry which has one wire for lock and another for unlock, while the 240sx has one wire which locks and unlocks. Bulldog suggests i need one of their relays and a 3 amp diode to get things to work. I don't see why the bulldog module can't just pulse the 240sx door timer via the orange/black wire. Don't see why I need a relay for small control wires.
