If your Probe does not have power door locks factory installed, you can easily add this feature to your car. Only five parts are required for proper installation (see Image #1, below). It's one of the simplest options you can add to your Probe while providing a slight increase to the car's value.

Overview

Normally the power door lock wiring is already factory installed, even in Probes without power locks. You should start by checking to see if the correct wiring harness is in fact installed. If it doesn't have the connectors, then you should be able to swap the harness with the one you need quite easily.

When installing the power door lock option, everything basically just needs to be plugged in. No additional wiring is necessary. When purchasing the parts from a junk yard or used parts dealer, make sure that both the door lock motors have the two mounting bolts and plastic connector on each of them (see image #2). This will aid the installation. Also, when purchasing the interior door handles with the power door lock buttons, be aware that the interior trim colors changed slightly between 1989 and 1990-92 Probes. For instance, the grey from a 1989 Probe is a few shades darker then the grey from a 1990-92 Probe.

Parts Required

Right & Left Power Door Lock Motors
Right & Left Interior Door Handles w/Power Door Lock Buttons
Power Door Lock Relay

Tools Required

10mm wrench/socket
Phillip's Screwdriver
Upholstery Removing Tool (Optional)
Hair Dryer (Optional)

Motor Installation

Remove the three Phillip's screws from the arm rest of the driver's side door and remove the arm rest.
Remove the Phillip's screws from the interior door handle and from the top front of the door trim, near the side mirror.
Remove the manual window handle from the door by removing the 'C' retaining clip behind the handle, then slide it off the gear. See Image #3, below.
Get an upholstery remover tool or something with a flat end. Slide the tool behind the door trim until you meet a retaining clip. Twist the tool to pop the clip from the door. Repeat for all retaining clips. If no tool is available, simply pull the trim away from the door, but be extremely careful not to break any of the retaining clips.
When all the retaining clips have been removed, slide the door trim upwards, to unhook it from the top of the door. The interior door handle will still be in the way, so when the trim is completely free, slide it back along the door handle rod to give you better access to the door handle. Turn the handle to the side, remove the clip from the rod by snapping it off sideways, then push the rod down and out. Remove the door handle and door trim from the vehicle.
Peel the plastic covering off the door interior. If the adhesive is dried out and doesn't peel off, use a hair dryer to soften it up.
Remove the plastic connector from the end of the power door lock motor marked with an 'L'. Slide the plastic connector into the hole at the bottom of the door lock mechanism in the door shell (see Image #4).
Slide the power door lock motor arm into the plastic connector. Twist the connector to lock in place (see Image #5).
Line up the two bolt holes in the power door lock bracket with the two bolt holes in the bottom rear of the door (see red arrows in Image #6). Install the two 10mm bolts.
Plug the power door lock motor into the wire connector (see blue circle in Image #6).
Reinstall the interior door trim and the new interior door handles with the power door lock buttons. Connect the interior handle wire connector to the wire connector show in Image #7. Install the Phillip's screw into the interior door handle and the other screws from the top front of the door trim, near the side mirror.
Slide the window crank handle onto the gear and reinstall the retaining clip.
Reinstall the arm rest and three Phillip's screws.
Repeat for the passenger side door.

Disconnect the trunk cover lift cords and remove the cover from the vehicle.
Remove the 9 push tabs from the rear trunk trim (trim opposite the taillamps) and remove the rear trunk trim from the vehicle.
Remove the two screws from the left side upper trunk trim. Pull away from frame to detatch retaining clips and disconnect the two wires from the trunk light (if equipped). Remove the upper trunk trim from vehicle.
Remove the remaining push tabs from the left side lower trunk trim. Pull the front section away from frame to detatch retaining clips and remove the lower trunk trim from vehicle.
Remove the three screws from the rear and one from the front/top of the left side rear passenger compartment trim. Pull away from frame to detatch retaining clips, but removal of trim is not necessary.
Locate the power door lock relay wire connector below the left rear speaker (see image #8). Connect the power door lock relay to the wire connector.
Press the left side rear passenger compartment trim into place until all the retaining clips snap into place. Reinstall the three screws at the rear of the trim and the one screw at the front/top.
Replace the lower trunk trim and press the front section into place until all the retaining clips snap into place. Reinstall the push tabs.
Reattach the two wires to the trunk light (if equipped). Replace the upper trunk trim and press into place until all the retaining clips snap into place. Reinstall the two screws.
