Where exactly does the LT4 KM plug into? I am pretty sure I know where, but I don't want to plug it into the wrong thing and screw up my pcm, so if any of you could tell me where it plugs in I'd appreciate it. Thanks

 

It can only go in one place.

Remove the PCM from the passenger side rear of the engine compartment, and remove the small cover on the back of the PCM. Remove old, replace new. Done.

 

alright that's what I thought, thanks

 

No problem.
