Just find the 6L and use your existing harness in your truck. Use Everything from your 5.3 and tune. It's that easy. I am in the middle of doing this now. Just cleaning up everything now.so basically if i find a 6.0 with harness and pcm the other two plugs will plug right in no problem and run the rest of the truck.
