Looking at that using the connector in this pic :
I think blue is GND, red is scl, black is +ve and green is sda. Do you agree using my previous pic?
Attached is a picture from the multiwii thread I've modified for you. I believe those are the connections you're looking for? Remember to connect the 5v and ground up to the rx as well
and connect the esc bec grounds up as well I believe.
