Re: Need wiring diagrams for 2016 6.0L/6L90 & E78 ECM

I’m considering do the same 6.0/6L90 with E78 ECM but can not find anyone to do the ECM reflash or the stand alone wire harness. Anyone have any success with these?

Try swap time on u-tube. Think he works on this stuff.

Any good tuner can do the flash and tune for you on that ECM. Just check with a local guy and you'd be set for any custom work you'll do, if anything other than removing the VATS. As for the harness, I did my own, but there's a guy who goes by Modern Vintage Systems on facebook and instagram that said he can do the harness for the E78 ECM. Most of the harness guys out there won't touch it.

I'm doing an L96/6L90 and used Easy EFI.
