I've never seen much difference in how those are hooked up, and I've 
never seen red boots. I wonder what those are.

The OE boots are black and grey/tan. There's a right and wrong way to 
install them, but I can never remember which way VW wanted it. It 
sounds like you've got things working again, but I can't help 
wondering if you bumped something else by accident.
