    L83/6L80 E92 Pin Out / Tune file

    Hello everyone.. looking for some help, did a search but nothing came up. I'm swapping an L83/6L80 into a 95 C1500. Can anyone help me out with a pin out diagram so I can mod my harness and a base map to get this beast up and running? Any suggestions, do's/don'ts with this swap? This is my first GenV. I sincerely appreciate any help.

    Thank you very much RC1. It seems my harness is a fair bit different. These diagrams appear to be 6.2, not sure if there's a difference in the 5.3 and 6.2. It looks like to me, after some more research, this engine I have is either a 2017 or 2018 (it has the 3 wire rail pressure sensor vs 4 wire on the 2014-2016).

    Yeah it is a 6.2, although I used it for my 4.3 swap and everything was pretty close. You're probably right about the '17/'18 vs '14-'16 differences.
