It is a bw josh, and the schematics and control module are all different.
The bw has a seperate sensor and motor, where as the nv it is all incorporated.
The bw transfer case can actually be relearned with a tech 2 as far as motor position.
Anything can be done. We have all figured that out.
First question I have would be will the tccm talk to the other modules on the older body style canbus? If the answer is no, than this is going to be very very involved and expensive.
How hard would it be to reprogram the tccm to control the bw and who would we ask?
