In anticipation of them disappearing again I ordered some adapters for the UMC. One of them was the unicorn 14-30 adapter, but I noticed that the other adapters (5-20, 6-50) are black and the 14-30 I got was gray. I thought the gray ones were the ones being recalled. Is there any way I can tell, perhaps with a serial/part number? I noticed that there is a long number lasered into the UMC side of the adapter. The number there is D17B0001424. I know I could call Tesla to find out but I don't even have an car order yet so it's not critical. I just like to plan ahead.
