Installing the one-touch feature on 95-99 Maximas using the AutoLoc WC1000 (link is external)requires you to change the polarity of the sunroof motor. This is because the motor runs off of a negative trigger and the WC1000 uses a positive trigger. This will present some problems. The sunroof motor will get confused in a certain position due to the polarity change.

For example: If your sunroof is open after you “one-touch” and you close it, you will have to “tilt” open and then close before you can one-touch open it again. This sounds like a pain but you get used to it. If this sounds like something you don’t want to deal with then don’t do this install. Other than that I haven’t had any other side effects. Now to start the installation.

Step 1: Remove the little “wings” on the side of the WC1000 and remove the dome light/sunroof switch assy. It is clipped in so use a panel puller or small screwdriver and gently pry it down on the dome light side.

Step 2: You will see a brown connector between the switches and the car’s harness. We’re going to concentrate on the harness side. Cut a slit through the black conduit and peel it back to expose the five wires. They should be black, blue, white, green, and brown. Green and brown are the slide triggers. You will need to cut the blue, white, green, and brown wires. (leave enough room on both sides to work with)

Step 3: Now connect the blue wire from the car’s harness to the white wire at the brown connector and do the same for the white wire (white wire at the harness to blue at the connector) Your basically just switching the two wires.

Step 4: Now you need to reverse the polarity of the sunroof motor. If you pull down on the headliner where it meets the sunroof you will see a blue wire and a red wire coming out of the motor. The blue wire is the ground and connects to the frame of the car. The red is power and plugs into a connector by the windshield. Cut these wires and swap them so the blue wire now receives power and the red ground.

Step 5: be retrieved from the dome light circuit. Peel back the conduit on the harness going to the dome light to expose the red and black wires. Tap into these for power/ground for the WC1000. Now connect the green wire from the car harness to the green wire on the WC1000. Next, connect the brown wire from the car harness to the blue wire on the WC1000.

Step 6: Now at the connector on the car connect the brown wire from the car connector to the brown wire on the WC1000. And then connect the green wire from the car connector to the white wire on the WC1000. You can squeeze the WC1000 under the headliner on the passenger side. There is room between the metal bracket and roof. You may want to insulate with foam. That’s it.

Depending on where the roof was when you started you may have to play with the switches to get it to orient itself, but the roof should now one-touch slide open and closed.
