I am working on tracking down a miss fire and over all poor running of the stang. have done all of the test and pulled the intake to take a closer look at the injector harness when i got the intake off i noticed that there is a broken wire. I took off the tape and plastic wrap. The wire comes from the white connector and the wire is solid orange in color. I was wondering if anyone had any idea on what this wire was for. I don't see where it goes and i have took all of the other wires apart in the harness looking for it. I am wondering if the wire is the ground? I didn't take any ground off from either harness.
