Any experience with 380hp mpfi conversion kit?

I haven't wired the obd2 plug in yet. Both ecm's were bought from summit new back when they were clearancing them out on sale. I haven't used them just dug them out of storage and tried for the first time this weekend.

I do have the complete instruction manual for them. Well I might try building a harness as per the manual schematic/diagram. Maybe there is a pinout or hookup difference I'm not seeing?
The instructions state the ecm's are loosely based on a 1999 ram ecm

Crazy usually the performance ecm's are very forgiving . They do have a sticker on them that says they need the vehicle reprogrammed. The sheet that came with the ecm's had a tech number that I called back when I bought them and the rep on the phone assured me that I could ignore the sticker. So maybe the rep was wrong that was like 5 years ago. Think I will go ahead and send one off to get checked. Maybe Summit sold me some bum ecm's or falsely labeled ecm's?
