Can any one tell me which green injector connection plugs where? I heard that these two connectors are interchangeable...Is this true? On a stock 1.5 liter Civic LX I have two injector connectors that are green... After we swapped engines this past weekend I mixed the connectors up...now i don't know which green connector goes where. I can't figure it out because they both fit each other and i want to be sure these injectors are wired the right way...but how can tell? Does it matter? Isn't one of the two injectors a Cold Start injector? The car idles with either combination of plug and play that i try? Oh yeah we switched a blown D15B engine for the same thing with only 80,000 miles I think the new engine is a JDM it has a silver valve cover instead of the blown original motor's black valve cover. Any help would be greatly appreciated.
