Lol that's a different approach I've never heard of. I found my wire strippers though. I was severely disappointed with the foglights I got though. I got some that said 6000k thinking they would match my HIDs at least in color & they're not even close!
Have tried 2 20 dollar sets of the H3 led bulbs and they are NOT bright enough to have any function OTHER THAN just looks! I have since then installed H3 HIDs in my fog lights and have had NO problems. To answer your first question, I just cut the pigtail connectors off of the car and also the HIDs and put butt connectors on since they are already on a switch.
