The lock physically does not engage nor does the dash light come on. No voltage to the diff lock button and no signal over the CAN. I am currently working on moving a bunch of SMT components between my original board and a donor board to see if I can get that resolved but I have a feeling the SW version will be the point where I fail to make this work because I don't have the ability to reflash and don't have the firmware for these.
