Cartman,
the install wasn't too hard. I'm really happy with the 2100's. The light they give compared to the stock lights doesn't even compare.
as far as mounting..there was a little custom work involved. once you remove the stock lights off the brackets, you will notice a hole in the back of the bracket...this is where the wire harness use to come through for the stock lights. unfortunetly, to make the new lights fit, you have to cover this hold to mount the new brackets over it. I used 2 metal outlet covers from home depot for this....I painted them black and screwed them onto the back of the stock brackets to cover these holes. (Once you remove the stock lights, you will understand this all a lot better.)
Now once they new plates were mounted, I centered the new PIAA bracket to this and bolted it down and attached the lights. If you want, I'll take some pics of the install and post them, it wasnt too bad.
As for the wiring, that was a whole other story cause I wanted to use the new relay with the stock switch by the radio...I also rewired the relay so it operates independly of the headlights.
You won't be disappointed with these lights..I highly recommend them...feel free to ask any questions you may have!
