You may want to contact Hotwireauto.com and speak with Chris. He is up to speed on these conversions. I know they use the 05 Hemi Ram computer pretty much exclusively for the swap. When I did my swap back in 2014/15 Bouchillon Performance had some Motorola guy program my computer but they didn't eliminate the battery ambient temperature circuit causing my system to tell the alternator to send almost 16 volts to the battery. I know there are a lot of data points in the computer not used but that was the one that reeked havok on my car til I got that fixed. I have since found that the Chevy guys have had the same issue with their LS swaps and ended up going to an external voltage regulator to solve the problem. As for the AC and power steering delete issues, I have no input since my car uses both.
