The option code for the NVG-149 would have been NP3, but as far as the noise is concerned, it could be as simple as you are causing the viscous coupler to go into hump mode if you’re spinning the tires viscously or a stretched chain. These things are pretty reliable, but they do suffer from the same type of issues that regular 4WD cases have plus the non-typical viscous coupler failure from time to time. It’s not 100% as anything can wear out, but usually failures of the coupler arise from abuse, whether it be from lack of servicing, causing the unit to overheat or humping the unit also causing it to overheat.
I did a search on NVG-149 and came up with this great article, if anyone is interested.

It seems that moderate amounts of humping are normal

I didn't have to do anything electronic with my swap. I had a manual floor shift four wheel drive transfer case. So all I did was remove the transfer case and front differential, and install the NVG-149 and front diff out of an AWD truck, plugged in the speed sensor to the port on the T-case and that was it, done.
