Wiring harness and computer
Hey guys, wondering what wiring harness and computer I need to use with a 5.3 and 6 speed. Also if later on down the line I swap a 6.0 with ls3 heads can I use that same harness. Thanks for the help!

Mostly will depend on the year of the engine as to what harness and pcm you will need as well as if dbw or dbc. If u plan to keep same gen 6.0 and same style tb you should be able to run the same harness and pcm (although will need returned obviously) and if u decide to go dbw u will likely need an adapter such as the x link when u go to the 90mm tb.
