what are the real differences in it? i've been told that i specifically need the rhd obd-0 b16a harness in order for everything to work correctly.

the setup/wiring/engine

engine is a first gen b16a, and i think my buddy threw away the engine harness that came with it when i swapped the motor at his house..


jdm engine bay harness, jdm cabin harness, jdm dashboard/gauge cluster harness

usdm b18a1 stock engine harness, usdm rear section harness (tail lights & fuel pump i belive is all..)

so far, it has a crank but no start condition, there's fuel pressure, but no spark. i tested using the screwdriver in the wire near a ground method, and nada. also, the ecu is not blinking or anything, showing signs of power/startup, even when you turn the key to the on position.

but, when i checked with a test light from the power to ground on the ecu harness, it has power.. and i've also checked incase the ecu was bad, by using another ecu i have, but it did the same thing.
