I see a wealth of information on swapping a gen 3 411 based drivetrain into a GMT400 but little to none for the gen 4 LS with E38 ECM. Has anyone had success with integrating it so factory gauges will work? I'm thinking of putting a 6.2, 6L80E and wiring from a 2011 1/2 ton 2wd into a 98 1/2 ton 2wd. I know you can do standalone wiring, but was wondering about gauges. TIA
