Maybe you should get it installed by a mechanic? You might want to search the sticky topics, but I wish I could help you, but that the best I can do.

Keep us updated on your progress, BUMP!

Are the "JDM" diagrams you have in english? If they are your diagrams are for the UK which are 90% accurate.

Do you have the wiring diagrams for your US car also?

Which JDM wiring harness do you have, the engine harness or bulkhead harness, many n00bs get them confused.

Is your JDM wiring harness uncut?

Make a list of all the pins from your USDM ECU and all the pinouts of the JDM ECU. Then you will go through and match up the pins US vs JDM. Like this one. http://scoob2.no-ip.com/dl/ecu.xls most of the wires in the top 26 rows will be direct cut and splice. It get tricky once you get into what sensors share what power sources and grounds.

it is from a jdm wrx ra 1994 and i have no wiring diagrams as of yet

So do you have the wiring harness that plugs into the injectors and such on the engine and the wiring harness that the ECU plugs into?

You really need both wiring diagrams before you can begin with the wiring.
