It's the fatter wire. At least i'm pretty sure it is.To test it is simple.1- Get a test light.2- Clip the alligator clip on the test light to the negative on the battery.3- Disconnect the injector connector you want to test.4- Turn the key in the on position with the engine not running.5- Take the pointy end of the test light and touch it to one of the two contacts on the injector connector of the harness.6- The one that lights the test light is the positive one. Done!!
