12200411 PCM swap for 1996 to 2000 GMT400 trucks

[Brian Brown]

Hey Swamp Thing can I get a copy of that pin out from you ? I also have a 97 c1500 that I would like to do the swap on.

just did the 411 pcm upgrade in my 97. Super easy and Jeff’s pin spreadsheet was bang on. Highly recommend this mod

The spreadsheet is lextech's intellectual property and he asks that it not be given out by anybody except him. Apparently he's charging $20 for it now. PM him with your email, truck year, engine, transmission, and drive. He'll email you back.

Cant blame him for this, $20 for the hassle to him seems really fair. I'm surprised he went this long without charging.

Thank you for replying. Sorry I did not mean to step on anyone's toes for asking for the charts. Thanks again

Hey guys,
I read this thread yesterday from beginning to end, I was sold on the upgrade by the first couple of pages, then around the 20th page, I was thinking that this lextech guy is going to be all used up and gone before the end of this thread!!!
Now before I bother lextech for my truck, I wonder if you could answer the "dumb newbie question"?
My truck is a 93 with a 5.7 tbi and 4l80e, I have a complete 97 donor truck with a Vortec 5.7 that I plan on swapping into the 93, including the composite headlight front end. Should I swap everything pcm forward (wiring harnesses and all), THEN tell lextech it's a 97? Or should I bore him to death (like I just did you guys) with all these details?

Get the pinout for the donor truck. You’re going to probably want to swap the entire fuel injection system, dash and interior. See my link in my signature about swapping from TBI to Vortec.

Looking, but not seeing a signature...
Dash and steering column. Check. I'm heading out to my dad's house Thursday to see what exactly I'm working with.

Hit the line in red that says "L29 swapped ", that'll get you to his build thread. Just tried it, works great
