2008 Under Dash Harness Differences

[moparmusclebiz]

What are the differences between the under dash harnesses between a 2.7 4spd auto car and a 5.7 or 6.1 with a NAG1 as long as the years are close. Say a 2008 2.7 Magnum and a 2008 to 2010 Charger 5.7?

Are there just minor differences or would it be better to just swap the entire harness?

I'm still going back and forth with what I'm ultimately going to put in it. So thanks for all the help with my questions.

Thanks,
Richard

Tell ya the truth, I don't really know. But I would grab everything if you are planning to upgrade from the 2.7 to the 5.7 or 6.1. All wiring harnesses, Nag1, ecm and tcm.

When considering a major drivetrain swap, if you don't already have the donor pieces, IMO you should hunt for a wrecked donor car - that way you have access to everything without getting nickle and dimed to death. Yeah, not everything will swap over and you may need this piece from (x) car and that piece from (y) car, and other modifications, but if you have most of your shopping all in one basket (complete wrecked car) you're miles ahead.
