After removing that pile of junk from under the hood, I held the new light up to see how it would mount. I usually just mount the light where the factory one was so I can use the wiring. Sometimes, I even get to use the factory bolt too. The GM light has three mounting tabs, and I usually just use two of the tabs with a couple of self-tapping sheetmetal screws to hold the light in. In this case, this Jeep had some underhood insulation that had to be cut out of the way. So, after figuring out where the light needed to go, I just traced the outline of the new light on the hood liner with a silver permanent marker and then cut the tracing with a pair of scissors.
