Yes, already swapped, now addressing harness, and as far as I could tell the best course of action was to just swap harnesses at this point and so I have almost completely removed orig harness on 2000..
Hello gentleman , new to site hoping to get some help, I have undergone the motor and trans swap on a 2000 3500, the 5.7 motor was shot and had a 92 454 motorhome donor, I thought I had read it was reasonably simple swap as far as harness to goes but doesn't appear to be , has anyone done this...
