Nv4500 swap. Now no cruise

I've searched and not found anything definitive.

Truck is 2002 2500. Had whatever automatic transmission came in that year.

I pulled the auto. Replaced with nv4500

Used 3 wire plug for reverse and ground to enable start

Neutral safety switch is on the clutch pedal and truck only starts with clutch pedal depressed

Trucks runs fine

Just desire cruise


Thoughts?

The neutral safety switch is probably telling the pcm it isn't in "drive". Not certain how to remedy that though.

Id say need manual pcm, manual transmission harness. And let bob wagner reflash ecm to manual.
