i just got a D15B zc non vtech (plan on boosting) im putting it in my 99 civic D16Y8 v tech (blew up) The zc should be OBD2 because the ecu i got with the swap clips into my brothers 96 integ. but it wont clip in to my civic is the civic a DIFF>OBD or what.Like i said its a 99.help me out Or could i just get a OBD2 weiring harness, like the one in my brothers integ,and would that work

Also are all the Honda ecu's made by the same manufacturer.Because the ecu for the civic and the ZC have IPT on the sticker with a bar code, and my brothers integ says denshigiken. It also does not have the cast moldings of numbers on the side like the other two. What do you think
