The advantage to me has always been the great folks on here. I went into this doubting ECM due to many years and lots of reading on here then when this happened, the first problem with my 04.5, I knew to depend on you guys for advice. I have learned a LOT from this website. Thank you sag2 and all that replied to this post. Sure is great to have my truck back. '04.5 3500 SRW, 4door, Cummins (as if there is any other), 48re, 3.73, foldflat, no mods, 89000 and looks basically new.
