I'm tryin' to determine what kind of PCM I have in my Ram.Is it a base or premium computer? I searched the web by part number and came up dry.The p/n is P56028.The reason I'm looking is bcuz I'm thinking of putting in an OTIS.I just don't know if this PCM supports it and I don't want to go thru the hassle of buying one and finding out the bad news.My truck is an 05 5.7 ST.I don't even know if it matters what base it is in regards to it being able to handle the overhead console.Are all the PCM's able too regardless of whether it came factory installed or not? Any help is appreciated.

 

There's 3 more numbers to your pcm p/n. '05 5.7's would either be a 958 or 957 along with your 56028. But you have an NGC III pcm either way

 

Very kewl.......TYVM.That musta been the 930AB.But there was a big space bewteen the 2 sets so I didn't put them together.
