In the first pic above, with the wires hanging down. The black box is the dash light dimmer. This is different looking than ones I have seen on ebay, which seem to have no plastic housing around them. Mercedes W114 W115 8 W108 W109 Speedo Dimmer Look | eBay

Any idea if this is correct?

And thorsen, I am enjoying it!! more every day!
