so i had both wiring schematics out and rewired a new ecm plug from truck to engine oem side i got from a old truck wired it accordingly it runs but i have no jakes and no cruise that’s all i need help with unless you have done this swap before
any information and advise would help me out so much thank you in advance !!!!!!

What I want to know is why did you go thru all that trouble?


You could have simply used the ecm and wiring harness off the CM2250 and had the existing program tweaked run the 2350 hardware and it would have run like a dream without any of those wiring or other headaches.

Now ... with the 2350 ecm and wiring harness, you have a mess on your hands. The emissions systems are not going to be compatible at all. ... which means that the truck has a delete programming? -- Which means that most likely it also has a horrible delete program now installed in that ecm to boot.

-- My suggestion is to yank off that 2350 ecm and wiring .. put back on the old 2250 ecm, wiring harness etc. ... it still should have all the settings and addresses programmed into it for the dash, cruise, jakes, truck etc. After that, just pull the program out of the old 2250 ecm using calterm and e-mail it to me ... I will help you edit it so it will properly recognize the 2350 injector trim codes properly and other differences so the 2250 ecm can run the the 2350 engine corectly.
