Go to the Section 8 of the Service Manual and find the Fuel/Ignition System wiring schematic. I don't know what year vehicle you have, other wise I would tell you what page to look at. All the injectors have a Dark Green w/Orange tracer wire attached to them. This is the 12 volt feed. The other wire to all of the injectors, have a different color. This is the transistor driver for each circuit. The diagram will tell you which number injector it belongs to. #1 = White/Dark Blue, #2 = Tan, #3 = Yellow/White, #4 = Light Blue/Brown, #5 = Gray, #6 = Brown/Black, #7 = Violet, #8 = Gray/Light Green,#9 = White/Light Green, #10 = Black/Light Green. Hope this helps
