A friend asked me to help him swap a 2016 Scat Pack 6 speed into his 68 Road Runner. He bought a complete (light front hit) 2016 Challenger from copart so we can have a complete take out unit and any of the misc stuff needed as well. I have been doing a lot of reading and research about what is needed and required for the swap. We have the keys, computers, etc and the car runs and drives.

My biggest question, and his too, is what harness to use? The Mopar performance one and the EFI source one seem like good two of the best choices from what I have read. So which one would you folks recommend for simplicity?

We'll run a Tanks Inc tank set up, Dakota Digital gauge cluster, and an Altercation front K member, if any of that matters. This is our first modern Hemi swap and I'll be doing most of the work.
