Quote: Does anyone have a pictures of a 411 LS1 PCM. I believe I have one out of a 99 silverado that had a 4.8 Unfortunately there is no tag on it anymore. Is it supposed to have 2 or 4 connectors?
I believe the 12200411 pcm uses two 80-pin connectors.
That's correct...2 plugs and a '99 4.8 would be a 411 PCM.
And thanks for the injector part numbers....good info!
