The wires exit were the factory parking light was located...
Now get a sanding block and sand down any parts of the remaining plastic lip, just because it is sort of a hack job doesn't mean it has to look like one. After cleaning the inside of the lens and housing with Windex (do it now, you only get this chance once) you can put them back together. One tube of Permatex ultra black RTV did both lights and matched the color of the Mercedes silicone exactly. Put the RTV all around the edge of the housing and slide the lens back on, we broke the clips that hold the light on so dry it vertically like this (i used a little added heat because my garage is below 40 degrees.)
After a few hours of drying put the light back in, the cover that goes on the housing will no longer have clips because we broke them, i installed some black metal mini hooks you can buy at Lowes or Home Depot. Just reverse the steps to remove the light.
And if all went well this is your end result. These cell phone pictures don't do them any justice at all, maybe tonight ill break out the camera and get some good pics.
So what's next? Well i found out the my ICM is going bad, awesome. The lights have been intermittent for a long time but i figured it was a loose connection. But after i get that replaced i'm working on rebuilding two of these. I'll post more about that when i get more of the parts together.
