This install took me approx. 5 hours but I hit a few snags along the way. Won't go into the details now but it is a simple mod to do and if done the 'right' way, then should take no longer than 3 hours to complete.
Instructions for the DEI 530t install:
1) Remove the three screws that fastens the door trim panel to the door.
2) Remove the mirror access cover ( one screw )
3) Pry loose the switch panel from the door panel. Use a flat blade driver and pop it free.
4) Now that the switch panel is loose, use a small flat blade driver and pry the door lock knob off the rod. Remove the lock knob.
5) Unplug the wire harnesses for the windows, locks, mirrors and remove the courtesy lamp from the switch panel ( push, turn and pull ).
6) Remove door trim panel by lifting it up and then away from the door.
7) Remove plastic covering on the door.
8) Remove speaker ( three screws ) and unplug harness.
9) Remove drivers side kick panel ( 5 screws )
10) Pull out both ends of rubber wire harness boot that goes from the door to the car body.
You have to run some of the wires from the 530t into the drivers door. A little tricky but can be done! Separate the wires on the 530t's harnesses that have to go into the door from the ones that will stay under the dash. The ones that will go into the door are the motor wires ( Up and Down Motor #'s 1 and 2 ), the switch wires ( Up and Down Switch #'s 1 and 2) and the orange 'ground when armed' wire if hooking up to a 'lock' input if so desired ( I did not connect this wire even though I threaded it through to the door. You never know, maybe sometime in the future! ) Now that you have the wires separated, wrap up about eight inches of the end of the 'door' wire bundle with electrical tape ( or any other tape you may have handy ). By pushing your fingers through the hole in the body where the boot was ( as a reference to where the wires have to go ), you can push the taped wire bundle through the kick panel area ( near the hood release ) and out the body hole. This was the tricky part.... while pushing on the wires from the inside, thread the taped portion through the rubber boot , then through the door hole and into the the door. Remove tape around wires.
Now, find a place for the 530t in the kick panel area ( beside the 'dead pedal' mount is good )
Now, look down from the top of the door and you will see a silver coloured part next to the window regulator. That is the window drive motor. There will be two wires from the motor. A dark blue wire and a brown wire. By reaching through the hole in the door where the speaker sits, get a hold of the motor wires and pull them down a bit so that you can work on them ( Do not use the dark blue and brown wires at the switch. They do not go to the motor! ). Cut both dark blue and brown motor wires in the door. Trim off about 3/8" of the insulation from all four wire ends. Cut the light blue and tan wires that go to the drivers door window switch. Leaving a length of wire on either side to work with. Trim off 3/8" of insulation from the four wire ends. The best method of making the connections is to use butt connectors ( I used blue 16-14 AWG ) with a crimping tool. Now make the necessary connections as per the 530t manual.
Okay, so now your motor and switch connections are done. Take off the dash fuse panel cover. Take the (+) 12v Constant, 20 Amp Fused wire from the 530t and thread it up to the fuse panel. push this into the 20 Amp 'Courtesy' fuse plug on the fuse panel. Replace fuse panel cover. Three more wires! All of them are ground. Ground Path Motor #1, Ground Path Motor #2 and Chassis Ground. Look near the hood release handle area and you will see a nut holding two factory ground wires. Loosen off this nut and put the 530t ground wires under the ends of the factory ground wires ( you'll know what I mean when you see it ). Then tighten the nut back down.
To test the system, plug the window switch harness into the socket on the switch panel.
Now the moment of truth! Turn the ignition to 'run' and try out your new toy. Praying as you do <img border="0" alt="[hail]" title="" src="graemlins/gr_hail.gif" /> . Driver/Passenger windows express up/down. Very cool! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
Reverse steps 1-10 and you're done!
Using these instructions and the 530t manual, you should have no problems. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />
Total cost: $69 + shipping (US) for the 530t and about $3 (US) for the butt connectors. I already had the crimping tool.
