Figures 1-3 show the device with 5 wires exiting the hole. Two blue go to the window motor, two brown into the plug, and one green/yellow (ground to the inside of the car). The box is slightly big for th e circuit board so it rattles if shaken.  The box is also not sealed either at the cover (held in by 4 Phillips screws), or at the opening for the wires.  Either these problems are easily solved or if you think that the inside of the door is dry enough you may leave as is.

INSTALLATION:

Place window in the fully closed position.

Disconnect the battery.

Remove the door panel as described in door panel removal DIY section.

Figure 4

Carefully remove the vapor barrier (Fig. 4). Although the picture shows I removed it from lower ½ of the door, only area around the speaker hole needs to be removed.  You also need to remove the insulation from the speaker hole.  Be careful as this is very fragile and although I tried to be as careful as possible it needed reconstructive surgery prior to reassembly.

The window motor is located directly above the speaker hole with the connection on the side (I believe it was toward the front of the car).  Reach through the speaker hole and remove the connector from the motor (Fig.5).  Connect two blue wires from the black box to the motor.  This is done by feel so remember the orientation of the connector as you are removing it.  The two terminals are side by side and although fig.6 shows the connection you cannot see it (taken with the digital camera in the door).  It does not matter which blue wire goes to which terminal.

Connect two brown wires to the plug (Fig.7)

Now comes the most challenging part.  Feeding the green (ground) wire through the rubber conduit from the door to the cabin.  First remove the two allen bolts holding the cover for the hood release.  Remove this cover and by pulling the carpeted sidepiece towards the back of the car it will come free.  What you see should be similar to Fig.8.

Fish the ground wire from inside of the door through the rubber conduit.  It should land in the vicinity of the brass plate that is grounded (Fig.8). Good luck fishing.  This was the most difficult part as the portion of the conduit inside of the car is very tight around the wires.  I used a 20-gauge single filament wire but if anybody has better ideas please donít be afraid to try. 

On the drivers side (shown) I drilled a small hole in the brass plate near its bottom surface and used a small screw to make contact.  Lower the hole; easier it is to work with. (Fig.9).

On the passenger side there is a similar plate but I opted to place the ground terminal on the bolt that is anchoring the plate (no drilling and easy to do).

Once all connections are made, take the window switch out of the door panel just by pushing inwards.  Connect switch to the driverís side window connector.  Connect the battery.

It is time for a test.  If the operation is reversed (window goes down as the switch is pressed up) disconnect the two brown wires from the connector and reverse them.  Try out the system again.

Figure 10
Note:  My driverís side window had a lot of resistance on the way up (middle 1/3) and the one touch up operation was not working properly due to high resistance.  To fix the problem I lubricated all the metal tracts within the door and adjusted the allen bolt shown in figure 10 moving it downward about a ¼Ē.  That solved the problem.

 
 

Figure 11

The box fits snugly between the door panels at the bottom and just below the speaker hole (Fig.11). Before permanently anchoring the box, test the window again making sure nothing gets in the way of moving parts.  The double-sided adhesive tape does a good job holding it in place against the outer door panel.

Use cable ties provided to tie up the wiring and move it forward in the door away from moving parts.

Reassemble the door panel.

Reassemble the side carpet & hood release cover within the cockpit.

Voila.

These are just authorís impressions.  Feel free to improvise wherever you feel the need to.
