B2725-Active Transfer Case (ATC) Mode Switch Circuit Malfunction
B0790-Transfer Case Neutral Indicator Circuit Malfunction

I recently had my cab replaced due to a accident. Before I never had a issue with 4wd. But ever since I got it back have had these codes. Replaced the switch in the dash but nothing.

I am out of town working. I am wanting to fix it now. 4wd comes in handy at work. It is my truck so it is my problem.

could it be where the motor is on the transfer case that engages or disengages the 4x4 where the wires plug into it maybe its unpluged.

replacing the cab would have nothing to do with the power train harness at the t case

Your correct in that but could it be bad or a damaged wire. Im sure the impact from the accident could cause that. I had an abs issue years ago when i got hit and it was a cracked wire that would vibrate and short out now and then that was caused by the wreck. It was just a thought anyhow. I know those motors go bad pretty often too.
