Thank you everyone for your comments especially Rawze.
I took the load to the original shipper and went home.
Here's what I did.
Took off the exhaust pipe before cans, unplugged DPF sensors, differential sensor on those cans, unplugged speed sensor on the end of the transmission right before drive shaft. Engine light was red. moved the truck back and forth couple of times. Let it ran for 20-30 min. started driving slowly with 4 way blinking.
