In regards to what? Are you doing a b swap on your eg and need wiring diagram or have you chopped your engine loom to pieces and need to re-wire?

More indepth info will get you your answer

Is your DC2R ECU OBDI or OBDII? Is the Rywire harness a mil-spec harness or just a replacement OBDI or OBDII OEM harness?

it is OBD II

i dont know how to answer that, but it allows the OBD2 ecu be plugged into the OBD 1 loom

Just tried this,
got some codes but when i cross checked it some of the codes didnt exist so clearly i had read it wrong ( tried like 5 times)

consistant one i got was 6, and 21

You got the rywire OBDI --> OBDII conversion harness. This may sound silly but is the engine loom you are using OBDI or OBDII?

Code 6 is water temp sensor
Code 21 is VTEC spool solenoid valve
