Will the transmission wiring harness from a two wheel drive work on a four wheel drive setup?

Good afternoon,

The simple answer is no. Part of the wiring for the 4 wheel has controls for the transfer case. The 2 WD does not have those controls.

The interior harness for the transmission is the same but the body harness is different.

I attached the diagram for the 4 wheel below.
