5.3L LM7 in a Custom Build-ECM questions Hello and thanks for taking time to read this.
I am putting a 2000 5.3L Vortec in a 1940's panel truck, that has an S10/Blazer 4x4 front end.
This is my first project of this complexity, and once I have the wiring harness adapted to plug the C2 into the donor 2002 4.3L relay box to power up the BCM, am wondering what I will need to do to the 5.3L ECM. I will have a custom exhaust with upstream O2 sensors, EGR had to be deleted due to clearance.
What else will I need to address?
Thank you!
