Dodge Rams R/S bypasses

Hi- I've had numerous requests for '05 and '04 Dodge full size pickup remote starts- I haven't done one yet- just need to know the preferred bypass modules for a "hemi" , a Magnum, and a diesel- is there any difference in modules, or will the same model fit all-- I see that they use the ring around the key method- is there not a Databusl bypass to "do it all"?  I like to research them before I try to do them in one session.  Any other hints/tips- how hard is it to put the ring around the key switch?  Thanks in advance for all your help- this is the best forum.  I already did a search for dodge- learned some but still had some questions.Brcidd - Engineer That Does Remote Starter Installs on the side.
