Hummer H3For the Hummer driver who wants the rugged look and off road capabilities of the Hummer, but in a smaller size and with a more fuel economy friendly engine.
what do you mean? the diagram you posted tells you that info right on it. the numbers going down the pcm are the pin numbers. it also gives you the wire color so you can cross check yourself.
i think it’s maybe the green one that shorting because i redid solder all the wires on injectors harness and if there’s is not good it will affect all of them since they all feed off the same source and they all were soldered together but the green ground is on its own that’s why I think its probably shorting somewhere maybe??
there should be the pcm connector pinout in the service manul.
i don’t think the car came with manual when I bought it but I’ll look around to see if I can find it after work. Thank you I will reply what I find later today
so I traced the line it’s good but what I found out that the main harness blue that goes into the injector harness plug is not making a full connection . The hole where injector 2 the green wire go to is too big so when you click it with vibration and such it loses contact. While the car was doing the misfire and the code I went and pushed on them together. And it went away instant. I confirmed that twice and it went away so I replaced the plug. And so far the car runs great. I’ll update a week from now as well

Why cut the entire connector? Light green/black tracer #2 injector, you only need to>

the rest didn’t look too good so just to be safe I just replaced them all also actual plastic piece won’t like click in good into the injector harness so I said to my self I’ll just replace them. The new connector came with all the wiring and it fits perfectly and clicks in place

That's an alternative as long as you properly sealed and protected the butt connections! I use
That's an alternative as long as you properly sealed and protected the butt connections! I use Solder Seal Wire Connectors along with Heat Shrink Tubing to cover the entire connection.
and I put heat shrink on top of it and also put wire harness tape all around . It’s very secure and I took a long drive and still no code still runs very good
