It's a tricky one this as its the same shape and size as the 583 b (5 pin), but as the pins are all in different places it won't fit!!
The porsche one (I think) is the same as the splitty type and that won't fit either, tried all of the normal routes Megabug, vw heritage but they only do the plastic type and although it has the same part number don't fit the bill.
Might have to drive around with me night vision goggles :shock:
