microsquirt install questions

Hey guys here from Australia, currently installing microsquirt I have currently wired everything up including the relays, fuses, trigger wheel, map,intake temp,coolant temp and 550cc high impedence injectors but have stumbled on CAS wiring and ignition output, i understand there are different inputs to choose from to wire to the CAS, i believe from the research iv'e done vr1 wires is the correct wires? im running the stock ignition coil with a PWR-2 , i know there's alot of older threads on the internet regarding mega/microsquirt installs, but there to old to provide photo's on those threads, maybe if you guys provide the answers ill draw a fresh complete diagram so people dont get stuck in this position!.

i was previously running nistune on my car but after going through 2 ecu's, 4 mafs and a patched 32 years old wiring harness i bit the bullet, i want something that's going to be reliable and easily replaceable, I'm not dissing nistune, just needed something newer to work with.
