ok, finally started my swap on my 9 civic to a b16b. have an uncut wireing harness that came with the engine, but the ecu they sent dosnt hook up. the numbers on it are 37820-pct-0031115-105034. anyone know what this ecu is suppoed to fit. it has b16b written on it in grease pen, but something tells me its wrong. only one plug from the harness fits ecu, yet it fits all three plugs from the d16y7 harness.....wrong year ecu?? please help cuze im literally at the shop workin on this right now. thanks a bunch guys

 

Nothing? ok how bought this. the stock d16y7 harness has 3 plugs that will plug into the computer that was sent to me just fine. the b16b harness only has two plugs that go into a computer?? that ring a bell to anyone?
