This might be common knowledge, but I never ran into this until working on my LMM today, so I figured I'd throw it here for the next poor SOB.
I got a limp and code that pointed to the infamous #2/#7 injector pigtail repairs. I ordered Bosch connectors with pigtails through an eBay seller. I started on #7 and it wouldn't plug in to the injector when I was done. I looked and found that one of the rails didn't line up from the new connector to the injector side.
Now to make a LONG story short, GM had a small run of the connectors on my truck, and you cannot buy them anymore. Even if you order the repair parts from GM themselves, you cannot get this connector. There is a GM Mechanic's note on the new part that tells you to take a razor and shave off that one rail.
I shaved mine and clicked it right in. The truck is running again
I can upload pics from my phone if anyone cares, but it'll be very obvious when you run into this problem.
Hope this helps someone some day.
