Just aquired this vehicle and the guy says he put a 6.0 out of a 2015 van into it.

The 4WD doesn't work at all no lights no sounds. I thru a switch at it and checked the fuses and relays.

I presume the ECM was changed with the motor. Does that mean the 4WD is now dead?

Is there a work around?

Help please

Have a qualified tech inspect/check the encoder motor for power to it and see if it responds to the signal.
