Need help with wiring questions

[THEBOSS383]

I am doing a Cummins swap/4x4 conversion. I am putting my Cummins from a 1992 Dodge W250 into a gasser 1990 Dodge D250 and converting the D250 to 4x4 using my W250 parts. What I am wondering is will the Cummins wiring harness match up to the cab wiring harness on the 1990 D250 at the firewall plug. Or do I need to pull the harness out of the cab in the D250 and replace it with the one out of my W250.
