Dan, I never saw anything that fit in there that came with the car and it wasn't on the RF parts list either. Check with Hershal and Mark W. too, two cars that also came over at about the same time, but I don't think people are running anything in those holes. I'm not 100% sure and Robert might have had different looms/parts for different markets, but I don't like Jerry's early blue car has anything used there either. They'd be pretty cool to use for twilight and DLR.
