Well I really tried not to take off the front bumper... But I HIGHLY recommend you do. Unless you have child sized arms and hands. I struggled to reach around the back of the bumper and barely got these installed that way.
All you need from this kit is the actual fog light lamps and the harness. The black plastics it comes with won't be needed. The bolts line up perfectly for mounting.
The wiring is a bit confusing. You will also need extra wire because it does not reach the battery with the harness it comes with. Also, its a pain in the ass to get the blank switch on the panel off to install this one.
If you're in the Whatcom county area, I may be able to quickly help with wiring if you get the front bumper off.
