Well here's my install of my LED bar. I took a few (crappy phone) pics and detailed the install for anyone who's never done it and is curious as to how to do it.
First things first, I have the MicTuning 30" spot/flood combo LED bar and a Tuff LED wiring harness.
The bar fits perfectly behind the two vertical bars behind your grille. I chose to mount it in the middle, so I drilled 2 holes. With a spacer ring on each side the fit was perfect.
Next I popped off the side of the dash and was able to feel for the clips and release the dash panel where I wanted to mount the switch.
Then I measured and marked out where I wanted to mount the switch and using a dremmel cut it out. Cut inside the lines and then you can slowly trim it up with a grinding tool till the switch fits.
