On the Dx there is a plug that has 1 Orange wire and 1 Black wire with a Yellow stripe, that plug is usually left for nothing. I think it is called a tandom valve.....it is only used on the Dx.(If i am not mistaken) Its somewhere around the middle of the firewall....so that plug doesnt go to anything..Your Eacv plug is usually has a green plug with 1 blue wire with a yellow strip and 1 black wire with a yellow stripe. Your intake air temp sensor has a white plug with 1 green wire with a white stripe and 1 red wire with a yellow strip.make sure you have them connected in the right spots. Your EACV on the si Intake is located on the backside, not far from the TPS sensor. And you Intake aire temp sensor is located on the right side of the intake manifold.Once you have pluged them in clear you ecu codes and see wut happens. You can clear them by removing the hazard fuse from the engine bay, or by removing the negative baterry cable. Remove for bout 15-20 seconds.
