A vin z 95? Are you sure that isn't a vin W?

And what is your question?? Sounds like you want to know the function of each wire at the PCM... Is there anything specific that you are inquiring about?

 

sup?, i am helping my father in law with his 95 blazer, and yes i was wrong on my last post it does have a w in the vin. lol. but anyway he put a 305 in and bolted it to the stock tranny and well the tranny doesnt go in low gear when you put it in drive am wondering how do we fix that? we were also wondering what plugs on the ecm can we unplug and it still run. please give me some feed back, it would be much appreciated. thanks.
