I'm about ready to do my 5.3 swap but have a few questions. Does anybody make a wiring harness to change your throttle body from DBW to DBC? Also can anybody tell me if I am missing anything, I have a complete 5.3 with all the accesories, the fuel line fittings in the swap post, and a tuned Pcm from Nelson. I am trying to change over to DBC so if anybody has any advice that would be great.
