I am not swapping a lt1. lt1swap . com just has the ecm pinouts for 99-06 vortec lsx motors.Originally Posted by skeet
I am swapping a 2003 4.3l to a 6.0l lq9 using a 99-00 wiring harness and a 0411 pcm.
It was my understanding that a 99-02 harness would be a direct replacement?
But if you look at the ecm harness pinouts from 99-02 none of them match the 2003 C2 under hood fuse box connection.

Has anyone done a V6 to V8 swap in a 2003 or newer truck?
What are my options for a PNP harness?
