Default 07 STI to 99 RS Swap -- Wiring questions

Wiring progress here:

Couple quick questions as I'm finishing up:
- B135-22 (STI) -> Acc. Pedal Position Sensor, Sub Power supply
- B135-31 (STI) -> same sensor, Sub sensor signal

Where do these go?

- B135-19 (RS) -> Green wire, goes to main relay. What do I do with this if I'm using the STI relays?
- B135-3 (RS) -> Grey/black wire, goes to the data link on the RS harness. What do I do with this?
-B136-15 (RS) -> Red wire, TPS power wire (branches out from 1 wire near the ECU to 3 wires). What do I do with this?

As Brydon said, B135-21 (RS) goes to the data link on the 07 STI harness. Can someone be more specific about this? Does it go to a certain pin on the data link connector, or what? I can't find a pin labeled "data link" on the STI ECU. Is that the SSM/GST Communication line?

B135-20 (RS) is supposed to go to the test mode connector. Do I just T it in on one of the test mode connector wires?

I also have 2 wires going to a little black box that looks like a fuse beside the ECU plug. One is Green/Yellow and the other is Blue/White. Where do these go?

Last question: A ground wire is a ground wire, correct? I can just attach these to any other ground of similar size (gauge) and it should be fine?
