Hey guys,
I'm going to be doing a 5.3 swap into my '63 chevy truck. I have all of the mounts figured out, I'm kind of concerned about the electronics. I have the harness, pcm, and it is all uncut. I'm going off the info at 2000 Vortec 4.8/5.3/6.0 Harness Info for the wires I'm going to need to use, but I am wondering about the VATS. How can I disable it, or who can?
