Fummins Low range on tcase

[dieselpolaris]

Anybody have any tips for making the 273 transfer case shift into low range on an 2007 f350 Cummins swap. Used an nv5600 instead of the 5r110. I know it uses a modulating signal vs grounded for neutral so wondering if there is a way to fake the PCM out to think it is in neutral. Thanks

We used the range sensor out of the 5r110 wired into the harness to make the PCM think it was in neutral all the time.
