Now for the install...
Disclaimer: I am not a professional mechanic or body shop expert. I'm pretty handy with most tools and I follow directions well. Never attempt anything that seems unsafe and always follow the directions or shop manuals when available.
Tools needed:
Masking tape
Drill/bits
Drop cloth
Various size screw drivers and/or interior removal tools
Anti-rust or paint equivalent
Sockets
Step 1: Remove the trunk lid liner
There's 10 plugs that need to come out. Be careful not force them as they can easily break. I used 2 small flat head screw drivers to gently apply pressure to 2 sides of the plugs.
These unscrew by hand and then gently pull out to remove.
The inside truck release and handle should pop out pretty easy.
Step 2: Prep/apply template
Go ahead and put your drop cloth in the trunk and leave some hanging out over the bumper and rear fenders to keep the lid from closing.
Make sure the surface is clean. Tear off about 8-10 pieces of masking tape and place them within arms reach. This will make it easier to apply the template.
Carefully align the template starting from the top and lightly apply masking tape in the designated spots. Do this with the trunk lid partly open. (Lightly because you may need to make adjustments to get perfect placement) Put a piece of tape under the template at the marking positions where you will be drilling later. Don't rush; once you are 100% satisfied with the template alignment move on the step 3.
Step 3: Drilling and sealing
Make sure you have the right drill bits per the included instructions. Drilling smooth metal can be a little tricky as the drill bit may want to walk away from the spot you are trying to drill. Just be careful and don't rush. I actually started with a smaller bit to get the hole going and then moved up to the proper size. Once you have your holes drilled you can remove all the tape and template. Smooth out any rough edges around the holes before you apply anti-rust/paint. Follow the instructions on the can for application, drying time etc. You do not want to leave bare metal.
Step 4: Fitting the spoiler
Once your anti-rust/paint has dried place the included plugs in the the 2 outside holes.
Fit the included clips and bolts to the inside of the spoiler. Peel back about an inch or 2 of the double sided tape cover (included on the inside) and fold it back over the outside of the spoiler for easy access. Without pushing the clips all the way into the plugs, check your alignment of the included clips and bolts. They can move around just a little bit. Carefully move the spoiler side to side so that it's perfectly centered. Once centered push the clips in a little further and carefully peel off the double sides tape cover starting on one side and then lightly push the clip in until you hear it click. Do the same on the other side and remove the rest of the double sided tape cover. Re-check that your alignment is spot on and then apply even pressure to the spoiler so that the double sided tape sticks well. Open the trunk and secure the bolts with the included nuts using a socket. Be sure not to over-tighten.
Clean up and enjoy.
