Plus motor mounts and that's all you need.

I think the cable runs up underneath battery, and the sensors and such are under there. Yeah, makes perfect sense to me too........

so i want to what would be the best way to go with the sensor on the pedal (04 to 05) or is it better without (03). I did notice that the transmission had way more plugs than mine, so i think thats were the difference is.

The 03 Hemi is the easiest to cover to the electronic system is under the battery. It used a cable then converts the cable to an electronic signal.
