Larry -

I'd probably take that deal, but I don't drive enough to ever actually wear out a Benz motor.

On the center vent, you're referring to the wiring for the bulb that illuminates the dial thingy, yes? There's a little trapdoor on the back of dial mechanism, right where the wire enters, that can be flipped open to remove the wire, bulb, etc. Just tape the wiring and bulb to the hvac box while installing the dash.

I'll vote with Peter to install the vent later. I know how fiddly they can be, with all the small parts to move the louvers around. It's a piece of cake to install the lighting after the dash is in, there's plenty of slack in that particular wire.
