Start by pulling out the upper center console. It should pop out if you pull hard enough. The way I did it was I stuck a butter knife in the lower corner and just started prying it out. Be careful, one slip and you could scratch something. Once the Console is out run THREE Wires down towards the original switch.

Here you can see the three wires I ran to the original switch.

Here you can see how I spliced the Wires. You will need 3 Spade connectors and 3 Female connectors. You can pick these up at Any Radio Shack. I've connected the Spade connectors to the end of the three wires I ran down from the upper console and I've also spliced another wire to them with a female connector on the end. One set goes to the switch and other to the plug that was connected to the switch. 3 Female connectors to the Switch. 3 spade connected to the plug.

Connect the 3 spade connectors to the original plug that was connected to the switch. Remember which wire is in which plug, you'll have to match the female connect to the original switch.

Here are the wires for the Switch. 3 Female connectors are needed here. Connect them the same was the original switch was connected. Once everything is connected it's a good idea to test it before putting things back together...

You can see the light blue female plugs, plugged back into the original spoiler switch. Make sure the female and spade plugs match the same slots.

Here's a close up picture I tried to take of the connectors plugged back into the original Switch. Sorry for the Blurry Pictures...

Everything put back together...
