Note: Part numbers sometimes change without notice. Always double check with your supplier that you have the latest part numbers. The switch is part number 996.613.155.00 A02 for a switch installed on the left side of the dash and 996.613.156.10.A05 for a switch installed on the right side of the dash. Like other dash switches it has a raised portion on one side. When you order the switch, ensure you specify which side you want the raised portion according to which side of the dash you are installing it into. These install procedures assume you will be placing the switch in the unused dash socket below the PSM switch on a RHD car. For LHD cars, the PSM switch is on the left side of the dash and the raised portion of the tail switch should also be on the left (as shown in the picture). For RHD cars, the PSM switch is on the right of the dash and the raised portion of the tail switch should also be on the right. Take care that you order the correct tail switch for your car. Parts you will need: 1 ea 996.613.155.00 A02 (or 996.613.156.10.A05) Spoiler Switch 5 ea Female connectors 5 feet (1 length) Connector cable 2 (3 inch length each) 14 gauge wire few Cable ties Tools you will need: Phillips head screw driver Blunt flat blade to prise the switch tab (I used a butter knife) Wire cutters Crimping tool Soldering iron Remove the cover from the fuse box. Then carefully remove the four screws pointed out in the picture. Ensure the screws do not fall into the fuses else you may start a fire! (The fusebox is located in the drivers side footwell.) Once the screws are removed, pull away the carpet trim around the fuse box. You will be cutting into the wiring loom connected to the existing spoiler (tail) switch. The switch is the black square item located in the bottom left corner of the fuse box. Note: The installation of the new in-dash tail switch does not effect operation of the existing spoiler (tail) switch. It is simply wired in parallel to it. I have used a mirror here to show you the back of the fuse box. Pull the connector from the switch. It has no clips but it may be quite hard to pull off. Be careful not to pull the wires out of the connector. DO NOT use a metal implement to pry it off. If you rock it from side to side while pulling, it will eventually come off the switch. Here you can see the connector pulled away from the switch. The connector has three wires: Green/black, Brown/Green and Brown. Carefully cut the 3 wires going to the connector. Ensure you do not short the wires as you cut them. Leave a long tail on the wires at the connector as you will need to splice them back later Use a blunt blade to carefully pry out the switch tab holding the PSM switch in the dash. I used alarm wire in a single cable. You need 3 cores in the cable and it needs to be about 5 feet long. Feed it through the opening for the PSM switch tab. You can see in the picture where you can feed it through the back. Push the wire through so that you can grab it from underneath the dash and feed it along within the dash to bring it out behind the fuse box. Carefully cut the 3 wires going to the connector. Ensure you do not short the wires as you cut them. Leave a long tail on the wires at the connector as you will need to splice them back later Fit the new tail switch into an unused slot. Usually the one below the PSM. Place the connectors as shown on the switch. Make a note of the colour coding you use and which switch terminals you put them on. I used red, brown and black wires in this configuration. Next you will wire up the tail switch light. Use two 14 gauge wires cut to about 3 inches. I used blue and brown wires. Strip both ends of the two wires. Crimp a female tag onto one end of each wire. Connect the tags on these wires to the two outer (remaining) tail switch tags. Pull off the connector from the back of the PSM switch. Insert the blue wire onto the left most PSM switch tag (blue/pink/brown connection wire). Insert the brown wire onto the top PSM switch tag (red/blue connection wire). Ensure the inserted wires are not shorting any other tags. Push the PSM connector back into place with the inserted wires. One way to do this is to cut the bare ended wires short and feed them through the tag holes before pushing the connector back on to the PSM switch. At the switch box end, feed a 1 inch piece of heat shrink sleeve onto each of the 3 exposed loom wires. Push the sleeves along to expose the bare wires. Pre-solder each end on all exposed 9 wire ends. Then solder the loom wires back together while at the same time splicing the new wires into the loom. The 9 wires comprise 3 from the original Spoiler (tail) switch connector, 3 in the loom that you cut from the tail connector and 3 that you have just wired in from your new tail switch. The wires are soldered as follows: red -> red/green black -> green/black brown -> brown Check the solder joints. Push the sleeving over the joints and use the soldering iron to heat the sleeving so that it shrinks around the solder joints. Ensure no strands of wires or solder is protruding from the sleeving. Refit the connector back to the original fuse box spoiler (tail) switch. It is important to tidy up your cabling. I used cable ties to ensure the cables don't rub on anything sharp. Before refitting the switch tab, test that your newly installed in-dash tail switch works. Also test that the switch light works when you turn your side lamps on (with ignition on of course). Finally, replace the switch tab in the dash, push the fuse box surround carpet back into place and replace the 4 screws. Job done.
