    With these injector harnesses, I've had the best luck load testing them (like pushbroom said). An ohm meter doesn't tell you much if a few strands are still connected. I disconnect the harness at both ends and jump 12v to each wire. At the other end load that wire and measure voltage drop. I use LoadPro test leads, but you can use a light bulb too. More than about 0.2 volts drop and the harness is failing.
