There are ways to wire it, but the best way is get the manual ECU. You should try to find a gen4 with a good manual trans but blown engine or rear ended or something and buy it as a parts car. Then you not only have everything you need, you also seee exactly how it goes on.
You need:
Trans
Flywheel
Shifter Cables/shifter assembly
Pedals
Wiring harness
Manual charcoal canister
That's actually I can think of...
