    Is there a way I can get a pin out sheet to swap a black box PCM from a 98C1500 to a 411PCM

    E mail Lextech for easy to use pinout spreadsheet. $20usd or go to lt1swap.com and cross reference the pinouts with a black box. and start swapping wires over to the new 80 pin connectors.

    Cool

    yeah shoot me a email

    you will also need to crank relearn
    i havent figured out how to insert files here yet so bare with me lol

    lmk if this works hpt has a relearn function in the vcm scanner there you will go to the little green button that says special controls and functions and go to crank relearn from there it will tell you what to do

    IF YOU HAVE CHECK ENGING LIGHTS THE ECM WILL NOT RELEARN FIX YOUR PROBLEMS FIRST

    This is a direct file from lextech. These spreadsheets he has specifically asked everyone not to share. Rightfully so in my opinion, Your not helping by posting this. Your showing how to disrespect Jeff and the people who helped him build this xcel spreadsheet by using this file as your own.

    Rarely have I needed to complete a crank re learn for a pcm swap. As long as the distributor is adjusted within 5 degrees + - cam offset, everything should be fine.

    why would i make this dude pay 20 dollars for something i already have thats like asking someone to pay you for a forum you decided to be in and give advice , i purchased this excel from someone else so i dont know who you jeff is and i own it meaning i can share it ?and if you put in a cam and new balancer ,rotating assembly ,crankshaft sensor or camshaft its recommended to do a relearn truck will still run without a relearn but it may cause other issues down the road

    Can someone put me in touch with lextech? I'm trying to get a pinout for my 1997 k1500 5.7 to do the 0411 swap. I'm new to the forum and not sure how to get in touch with him. I'll pay the $20 just need to get in touch with him. thanks

    I've been trying to get ahold oh him now for about 3 months for a pinout. He must be a very busy man. So finding this thread with the 1996 truck pin out that i need is a blessing right now. sorry and thank you at the same time. He must be busy or going threw something to not be able to answer. Thanks again marcodiazc158@gmail.com
