Power Lock and Keyless Entry Installation instructions: Mazda MX-3

Door Lock Actuator Installation:


Unscrewand remove the inside door handles.



Pop off the speaker cover.It is held on by 4 plastic joints that pop off when you pull.

Pull off the inside of the door.Start by pulling on the bottom of the door, unpopping all the joints.Then lift up on the panel, and it should come right off.Carefully remove the plastic on the door.

Drill the three holes to mount the actuator.Note that there are two straps mounted in a T (see the left picture below.)

Right now the goal is to make sure that everything is moving freely.

Install the piece that attaches to the power lock rod to the manual lock rod and make sure that everything is moving freely. (See above right picture.)

Do not reassemble door until after you have tested the system.


Wiring Installation:


Install the keyless entry kit and relays under the dash in the vicinity of the steering wheel.You can install it wherever you want, but it may be easiest to install under the steering wheel.

Hook the positive wires to a positive source that is always on.The radio is a good source for this.††

Run the Actuator Wiring to the doors.These are the red and black wires in the gray sleeve.Donít try to get it through the door, yet.

Running the wires to the doors is done in two steps.First of all unsnap the black rubber wire tube from the frame side of the car.There should be wires inside.Undo the white piece also (inside the end of the black tube).

(Shown is the black tube and white insert)

The first step is to get the wires going from inside the car out to the opening by the door.Using the conduit, snake the conduit up and out that opening.This is done starting from underneath the dashboard.You will have to stick your finger in the hole in the frame by the door to guide it.You are using both hands, your left hand on the inside of the car, and your right hand on the outside of the car.Then when you can grab the conduit through the frame opening by the door (with 1 or two fingers), tape the wires to the conduit, and pull the conduit and the wires through the opening.


The white thing is the conduit being snaked up through the hole on the inside of the car.Pic on Left shows the conduit going from inside the car through the frame and out to the space between the car door and the frame.This is your goal.

The pic on the right shows the wires being taped to the conduit.†††††††


Secondly, starting from inside the door, snake the conduit through the rubber tube and out the top of the rubber tube.Then tape the wires to the conduit and pull the conduit back through


Hook the wires actuator wires up to the actuator, compress them lightly with some pliers, to make sure that they stay attached, and then tape them up, to prevent the metal from contacting other metal and shorting anything out.

Repeat the procedure with the Passengerís side.You may have to unbolt the fuse box.


Note:When you are testing the lock/unlock functions, it may be necessary to reverse the lock actuator wires to get lock and unlock to work correctly (instead of backwards).




Power Trunk Instructions:


Position the actuator on the passenger side of the trunk lock.

Unbolt the trunk lock.There should be one rods and one cables connected to it.You will be connecting the power trunk cable by drilling a hole, filing a notch or attaching in another way.

The pictures above illustrate the basic principle.You will need to hook up the positive, negative and lock wires.Run the green wire underneath the seat belt, and under the cover on the bottom of the door opening.Then attach the green wire to the power trunk wire of the keyless entry unit.††††††




Instructions For Push Button On and Off Buttons:The buttons should be wired into the Black wires coming out of the relays.Find a suitable place to mount the buttons, drill holes and install.The other wire coming out of the buttons is wired into ground (-).
