5.7 Hemi Conversions - XVMotors? Arrington Chip Killr? Other options?

Agree with Joe,

http://www.hotwireauto.com/ .......these guys make the harnesses for Street and Perf last I heard. Probably be cheaper buying from the builder.

You can also call Dave Weber at Modern muscle...he has done several harnesses, he likes AEM systems

Fastmanefi.com ....he builds FAST systems for GenIII.

Three options I have been considering for my GenIII wiring/ECU
