engine harness wiring question.

[s'ko]

I have an 92 EJ22t and I am swapping it into a RX.

I pretty much finished stripping down the engine management wires and stuff away from the body harness and I have three wires that I need to ID.

They are white-green, green-white and black-green. I think they are coming from connector b15 (square 12 pin gray connector) in the FSM wiring diagram but I am not sure. I look at the FSM and I can't find any of those color combos for B15.

Anyone have any idea what these are for?

Thanks
