What are the differences besides the interior and ECU plugs? Can I just swap my 3G plugs onto the 4G harness? Are there any pinouts for the two with colors?
Basically I have a car that originally came with an 8 valve motor. I took off the 8 valve head and put a 12 valve in it's place. I don't have a 12 valve harness. I have ALL of the parts for the 4G37 but I NEED a 12 valve harness. Can I convert the 8 valve harness to a 12 valve harness using this 4G 12 valve harness that I have here? Is there ANYTHING I can do? Nobody can find a 12 valve harness for me.

I would convert the 8v harness using the connectors from the 4g harness. Not sure if the colors are the same or not.
