    So I don’t know what that is as I am not familiar with any thing newer than the black box for the vortec and I know they call the 1 I’m going to is referred to as the “411” ECM and was used on both the vortec and LS engines. I have a diagram but it doesn’t show all the pins that are used for my 98 k3500. So if that’s what you have I absolutely could use it. I would think that the newer ECM would have more separate return wires for the sensors instead of having them all solder together

    Hello, who can help me with a cable diagram to change the pins for a PCM Black Box Blazer 99 4.3 v6 to 0411. I am from Venezuela and I would like your help. I also want to put a set of ls1 coils on it and I think I should use 60-2 crank trigger wheel?
