Hi,
I have just installed the same kit.
I also have a kufatec MDI loom, but have not dealt with that yet, while I get the BT working.
One should plug into the other but I notice there is a blanking plate on my MDI loom which confuses matters.
Coming off the main connector in your picture should be 2 white 2 pin connectors, one male one female.
You will then have a microphone with cable and connector. This connects to the two pin connector with the white wires in your picture.
The other connector has grey and purple wires, this connects to the black shielded cable which runs down to the blue tooth unit.
You then have the blue tooth antenna (if you have the same kit as me) that plugs into the bluetooth box.
See the thread here for a guide on fitting (the only difference is that my kit has a separate antenna to be routed up the drivers a pillar and mounted near the windscreen):
