Ok are the wires that are in the harness different colors than those in the civic? I didnt pay enough attention to detail, but now that my car wont start up.... detail comes into serious play. In my 91 dx crx harness, the pin positions c1 has a orange wire coming out of it, c2 has a green wire coming out of it. Also, b10 and b12 have wires in them already too.

Does someone who has completed a mpfi swap on a crx have pictures of the ecu harness so that I can figure this out tonight? thanks

 

So the pins u need to ad to the ecu for the mpfi swap are already being occupied? Some of them should be open (not being occupied). I remember when i did the swap on a 91 civic hatch STD, 1 of the pins had a wire in it already, so i just depinned it and left it out, then plugged in what i needed to ad and it worked fine.

 

Nevermind... my bad I already swapped em myself earlier....
