Only 2 brake lines are needed to be swapped. Both are for front wheels, as on MK60EC1 they are other way round.
You will also need a bracket for MK60EC1 pump from mk6 as MK5 doesn't fit.
Did this swap in my car when I was fitting color cluster. Not sure about Gateway as I fitted CH just before the swap.
Reason for a swap is that MK60EC1 does have different pin outs then MK60 (yes, you need to change pins in your plug as well)
Below how to connect new ESP.
