5.7 Throttle body
If you are using the factory computer you must use a drive by wire throttle. Hemi's only came with DBW from the factory. If you want a cable operated throttle you must go to an aftermarket ECM either AEM, FAST, Megasquirt, or some other similar ECM. As far as I know, no aftermarket ECM uses drive by wire.
