Default Link ECU on 2003 Impreza RS Wiring

I have a 2003 Subaru Impreza RS and I'm wiring up a Link ECU to take over the fuel etc. management while maintaining my stock ECU in place. This is straight from the AVO turbo kit.

The wiring diagram included was from a 2000 RS so I printed the 2003 Subaru impreza RS wiring diagram and hooked eveyrthing up except:

Where do I draw these from:

- 12v power
- power ground (we have chasis ground)
- ignition 1 (it uses wires 1 and 2, one of them (i believe 2) we dont know where it is on ecu plugs)

it said in my manual, which makes the most sense, to run a dedicated power line to the unit and fuse it, i just have a wire connected to the wing nut assembly on the positive lead of the battery post clamp

the neg u can use a good chasis ground or theres a few wires on the ecu...thats all i got
