I tried that, it wouldn’t communicate regardless of the year selectionSo, fool it.
That’s what I meant by fool it.I tried that, it wouldn’t communicate regardless of the year selection
But, if a 98/99 pcm is plug and play I might try that. I need a 5.7 engine tune anyway.
So I just messed with it tonight.. I don’t currently have a truck to test it on right now. My new 93 is all apart. Once I get things back together I’m gonna have to bleed things anyway so it’ll be a good test.Still gotta mess with it guys so sorry.. lifeeeee friggin lifeeeee
FSM should have a pinout that tell you exactly what every pin is used for. That would be the only place I trust for info like that.So I just messed with it tonight..

Does anyone here have good knowledge of these scan tools? One of the pins on the main data connection (the 16 pin) is broken / bent. I want to know if that’s even used. I know in some serial connections, certain pins aren’t used. Hopefully this one isn’t used..
For the truck or actual scan tool? I’m talking about the scan tool connections.FSM should have a pinout that tell you exactly what every pin is used for. That would be the only place I trust for info like that.
