i just put the engine back into my car after building the block i have put 100 miles on it and the check engine light comes on it feels weak and powerless also at no matter what rpm im in if i put the pedal all the way down it sounds like the vtec is trying to kick in, i want to check to see what codes im throwing but i cant find the plug... chiltons says its either above the ecu or center console way under the dash i couldn't find it. neither could my mechanic, i need to find that and put a conductor (like a paper clip) in there so i can read the codes... can you help me find it?

 

ground the wire on D-4
