i just did a b16a2 swap in my 96 ex coupe. The problem im having is the ecu is missing one of the plug, i have the green, blue, and gray, i think im missing another gray plug..I also have a check engine light on, plus my rpm gauge is not functioning. any ideas?? right now i only have two plugs going into the ecu, and the green one that plugs into the other green plug. Is there supposed to be three? im confused...

what year is the car? what year is the b16 and harness what year is the computer? also if you had a d16Z6 you can use that computer till you get the problem fixed just the fuel curvs will be off....

car is a 96 ex, motor is a us b16a2. Im running a p2t si ecu. i cant use any other ecu because my problem is the harness from the engine it's only got two plugs for the ecu. i believe its one of the gray ones. I looked at my y8 harness and its got three plugs. Im missing the left plug on the ecu. any ideas, car runs and idles, but i still got the car on stands until i find out what the hell is wrong.

well every harness I have seen has 3 plugs... I dont know what you have going on but I would pull out the old harness if you have it and check it out you can use the Y8 harness if you had a Y8 < vtec 1.6 ex motor > or you can look at the old harness and see where that plug go`s also unless you putting a vtec motor in a no vtec car you dont need to change the part of the harness that go`s into the car.... simply un hook it under the hood... atleast thats what I did check yours out if its the same use that part of your pig tail and plug it in to the B16 harness.... just trying to give you the only advice I can not a motor swap pro but thats where I would start... good luck buddy
