Mercedes offered paired breakout leads for CAN diagnostic use on a various series of vehicles, including W202, W208, W210 and W220. These leads permitted connection to CAN B (220 580 00 99 30) and CAN C (220 589 00 99 31) X30 connector busbars located in the passenger door sills.

Unfortunately, neither of these wire sets fit the X30 connectors on a W221. Is there a dedicated lead set for the 221 chassis CAN and, if so, the part number? Thanks.
