Dash Spoiler Switch Hack Instructions?

Recommended Posts


I assume you have chosen a spot in the Main Instrument Cover (surrounding the Climate Control). Since you'll be working with the car's electrics, it's best to disconnect the Battery (be sure you have your radio code).

Next, remove the Main Instrument Panel cover by carefully prying it from the bottom (you may be able to do this with your fingers, if not, carefully use a small screwdriver. The cover is just snapped in place.

Now, remove the blanking plug for the hole you've chosen, again a small screwdriver from the backside and pry the blank out. Now install the switch from the backside of the Instrument Panel and push it firmly until you hear a click and it's flush with the Panel. Route the wiring harness to the left, under the dash (using wire ties to secure it) and down along the left wall by the Fusebox. This harness should have 3 longer wires (Red, White, Brown) and 2 shorter wires (Red, Black).

Remove the Fusebox cover and remove the 4 Phillips Screws holding the Fusebox in place. Run your wiring behind the carpeting and behind the Fusebox. Pull the electrical connector from the back of the spoiler switch. You will see 3 female connectors inside - 2 parallel to each other and one perpendicular to the first two. Hold the connector so the 2 parrallel connectors are to the left. Now plug the Red wire connector from the Wiring Harness into the top parallel connector, Plug the White wire into the Bottom Parallel connector and finally the Brown wire into the remaining (perpendicular) connector.

Carefully tuck everything out of the way and reinstall the Fusebox using the 4 Phillips screws. Reattach the Fusebox cover.

The remaining wires in the Wiring Harness (shorter than the other 3) are the Illumumination Wires to light up the switch. Using a crimp connector (or splice) attach the red wire to any Blue/Gray wire and the Black wire to any Brown wire near the Radio Panel. For simplicity's sake, you can trace the Illumination wires from another switch and splice into these. (or you can simply not illuminate the switch). Push Main Instrument Panel back in place.

Now, reconnect the Battery and check the switch for operation. The switch is a Momentary ON switch, that is, you must press and hold the switch until the spoiler is fully extended/retracted. You can hear the spoiler raising, or simply hold the switch for a 3-4 count (sufficient time to raise/lower the spoiler). Punch in your Radio Code and you're done.

Happy Motoring!... Jim'99
