OK, here is another schematic:
the key is the light green and light blue control circuits......
What is confusing about those injectors is they are not really in the place that they actually look....if you look at the lower intake you will see a casting number(from 1-6) that the injector hole actually feeds(kind of crosses over to the opposite side)....so look at the "runners" in the lower intake going to the injector holes, and you will see the casting number of the cylinder it actually feeds...the even numbered injectors will have the light blue control wire, and the odd numbered will have the light green.....power feeds in this harness are pink for 1-3-5, and yellow(in your case) for 2-4-6......
However, the ohms reading, directly from each injector should be 12 ohms.....an ohm reading from yellow to light blue, should be 4 ohms(with injectors connected, but main harness disconnected.....4 ohms from pink to light green.....
