Hemi Swap Complete - 2002 4.7 to 2003 5.7
#81
Instead of rebuilding or replacing my 4.7 (after the head gasket blew) with another 4.7 I'm doing a 5.7 swap as well. My donor truck is a 2004 2wd QC Hemi Ram. My truck is a 2002 4x4 QC 4.7 Ram. I pulled all the wiring from under the hood to under the dash w/ the electronic gas pedal, the engine w/ all the accessories, motor mounts and the cats, the computer, the power distribution center, the evap system and the radiator from the donor truck. I'm in the process of pulling the engine and everything from my truck. I will keep updates as I continue with the swap. I will post pictures also.

Gas Pedal
Hello I just started doing a swap just like yours i got a 2002 2wd 1500 with the 4.7 and got a whole donor truck 2003 2500 2wd 5.7 hemi. I have the motors pulled and pretty much ready to go but i wanted to know to get the pedal assembly out do i have to take apart the dash? is there an easier way but will i have more problems? If it takes more work to get the whole pedal assembly out but les hassle in the long run id rather do that. Any thing you can provide and if you got some pics that would be great. Thanks in advance.

Item list
Had a radiator hose blow out while my wife was driving. Motor over heated and now blown head gasket has led to more issues. Currently have an 02 with 4.7 wanting to swap to a hemi. This would without a doubt be the largest undertaking of mechanical work I've undergone but I have a friend who has done stuff like this before. Is there someone who might be able to give me a detailed item list of everything I will need. This way I can start looking for and pricing items.

hey franklin, from my understanding from the first page they say to gather: motor, harness, mounts, pcm and ecu, sounds like the dash harness doesn’t mactch up with the harness from the hemi, myself I was wondering if it would be easier to pull the dash/dash harness too...there was a few other small things mentioned also but have a look at the previous posts. I’m looking at doing the same swap also, I have a 02 4.7L with the 5spd NV4500 tranny w 30,000kms

Apps connector questions
I realize that this is an old thread but worth a shot,
I have an 03 ram 1500 4.7 and recently dropped in a 2003 5.7 hemi. I am in the process of installing the apps along with the connector. I removed the old cruise control servo. How did you run the wires to make the connector work?
I have the connector that plugs into the apps from the hemi...glad I got it snipped and sent with the motor so I have some wire to work with.
you wrote that you ran 6 wires? Did you cut and connect to the previous existing harness from the cruise control connector?
Any help would be great.
Thanks!
