Is installation hard?I bought one from Spoiler and Wing King: Custom Car, Truck and SUV Spoilers, Body Side Moldings. He sells on ebay too where I bought it for about $100. They need the external paint code of your car to send you the exact color spoiler.
I got my ext. paint code from the sticker on car body. You can see it when you open the driver door, near the bottom.
I installed it myself. Ask me for any installation help.
What did you use to drill the holes?It took me 1 hr to install. The difficult thing is figuring out where to put the holes in the trunk. The spoiler generally comes with some guiding stuff. You need to tape them inorder to find correct positions.
Yes, you need to make holes in the trunk. Be careful while doing that. Make sure the positions are correct.
Regarding the wiring, you need to make another hole for the wiring to reach inside the trunk. Splice the brake wires and connect the spoiler wires to them.
