Well, anyone looking to do an OEM part fix should know that the grommets where the wires go up are actually part of the wire and are able to be pulled with some prying fingers.
They have a click connector on the end that can be reached by removing the spare tire. Just to the left and right of the center piece there are openings and a small white tab. Pinch these white tabs to let the wire away from the metal, you can access the wires from the opening. Pinch apart the now showing connectors here and your ready to put in your new wires.
Had me baffled how i'd put in the new wires for a little bit, but really easy after i found access. The new wires come preassembled with the bulbs and lens cover held together with the bolts, you need to thread the wires through the mounting bracket and through the original holes.
Just thought i'd throw this in here just in case someone didn't want to go splicing wires.
