Stupid Question off a 1991 CRX D16a6 Anyone know why cut off injector plug-ins from a D series DOHC would not plug into a D series SOHC injector?? I bought an engine from a guy and he threw on some fuel rail from a??? which did not fit even close so I found a rail and cut off fuel injector plug wiring off of a DOHC (plugs for the DX to SI convers.), but now the new plugs won't plug into the injectors I have on the engine. So I am not sure if I have the wrong injectors (if the guy just threw on some off of a pile he had or what), or are these plugs I got wrong. Can't find anything on the net on plug differences, so i was hoping one of you guys might know something. Any input is greatly appreciated. Thanks!
