Good day DK member

I am trying to read a 2014 VW Polo MCU - D70F3423 with CG100X but my circuit board is different to their diagram.

I have looked at Xhorse diagram and there is FLMD1 extra cable compared to CG100X

Anyone know what that extra cable is on CG100X?
I've tried reaching out to them but it seems there is a language barrier.
