I got myself a spoiler but I need to install it now... the question is should I take it to a body shop to get it done, have one of my friends who might be good at that sort of thing do it or should I attempt the process myself? What steps would be required... just drilling the holes and plugging it in?

 

pretty much, but make sure you have exactly where the holes go and a drill guide. ortherwise your drill will slip.
Always have a friend there to help you. You want it perfectly aligned. Measure and measure again.
You should be able to do it yourself, but if you have any doubt get someone else to do it.

 

I have the thing installed, but I haven't connected the wiring yet to the brakes. What would be the best way to go about doing that? Any ideas from anyone? Thanks in advance!!!

 

use those splices that just clamp onto the existing wires. If your not too knowledgeable about soldiering this is the way to go. If you can't figure out which wires to splice just lemme know and ill send you a pic.

 

measure once and drill twice, you will be good.
