Hello, I put an 01 5.3 n my truck and am going with the stock ls harness. On a budget. I have a manual trans, nv4500. A work truck. Do I use the starter wires from the 71 or use the ls harness? How about the ac? I plan to go with the round Vdo gauges , and how do I wire them up? I will mount the ls computer in the stock location. Will I need another fuse block? Is there any info on this that someone has posted? Thanks for everyones help, past & present. Alan
