I did! I looked over the wiring diagram thoroughly and tried troubleshooting it that way, but it was getting way too complicated. Then, I got lucky! I was walking through a Junk Yard that I frequent, and low and behold, there was a 03 Dodge Ram that had once had a 5.7 in it. The engine and tranny had already been pulled, but the Power Distribution Box was still there along with the harness for it. I pulled it and put in in my truck and bam....it shifted properly! Thanks for everybody's help.

 

I too have a '03 Ram 4.7 that I want to convert to the same year Hemi. From what I understand, the following parts are what you used:
'03 5.7 Hemi engine and wiring harness
PCM
TCM
Power Distribution Box and wiring

Aside from having to wire up for the electronic TB, is there anything else you had to do that involved the TB, for example, the pedal assembly? What about the radiator and a/c?

Everything you have done is almost basically plug and play for an '03 4.7 swap to '03 hemi from what I understand, with the exception of the TB.

What kind of mulah did you spend for this entire project?

My engine is approaching 170k miles, with less than 5k miles on the heads. So, before spending all the $$$ for another underpowered 4.7, I'd rather spend about the same amount for more power and ability.

 

If you do , I hope you start a thread and post pics..

 

Very COOL ! I'm glad to see you got it going..Have you driven it much ? How do you like it now with the Hemi ?
