    Engine Swap Issues

    GM folks.

    I just did a swap on my 2013 3500.

    Dropped a reman 6.7L long block in it.

    Tried to crank it last night an I'm getting service 4x4 something bout abs, and my factory stereo says something bout antithetical code and it will not turn over.

    There is one lil round red light that flashes the whole time the key is on.... help!!!!!

    Will I have to have my ECM reprogrammed?

    It was showing no bus on the odometer and now it doesn't say that anymore.

    Just service abs and service 4x4.
