This way if it's bad (it's not uncommon for them to be bad right out of the box) they'll know right away and you won't be stuck with a $2K paper weight because as we all know " there's NO returns on electrical parts.
Also you'll have the correct program for your truck and all the switches working so you don't have to fight that.

Like mentioned above... TAKE THE OLD ONE TO AN OEM STEALERS$IT for the certified for that TRUCK make/model... not to a cummins shop ... and have them bench flash the new one and restore your old settings into it while they are at it.. You don't want to buy a blank ECM and take the chance it is bad out of the box... That few hundred bucks extra that you spend to have it pre-flashed is cheap insurance against these kinds of problems.

This will also ensure you have the latest software for the truck and engine. this is very important too.

If the truck needs the programming adjusted for a de-mandate, then that is a very simple matter to overcome around here.
