Thanks, I am not sure which one is the x connector, and what pins should I use from the B1, C1, and M1 onto the X connector?They're all the different junction blocks in the footwells and the engine bay. You don't need any of that. Everything you need to inferface with is on the B1, M1, and C1 connectors on the 7M harness. Most of what you need on the MK2 is on the X connector.
