What vehicles had the 545rfe?

I have a 5.7L Hemi motor and I'm trying to locate a transmission that will work with that I have.

I have a 2005 Ram 1500 RWD computer and will be buying a wiring harness from a vendor.

From what I've read most vendors sell the harness for the 545rfe trans. I think this might be the best bet for me. Although the 45rfe isn't much different.

So will the 45rfe bolt up to the 5.7L? Will it be able to hold the power? Will the 4.7L transmission work on the Hemi? I've read it's the same transmission with different computer programming.

Anyone have more knowledge than I've been able to find?
