I have a 1999 F350 XLT Crew Cab Long Bed Dually 7.3 diesel with keyless entry, power windows/seats, and 4x4. The 4x4 does not work. The GEM in the truck has already been replaced by the previous owner due to water leak, and I think it’s the wrong part number. Dealership said they cannot reprogram the module as the software for it is obsolete. Does anyone have the proper GEM part number for this truck? I can PM VIN. Thanks!

F81Z-14B205-EE is for 4x4 (with or without ESOF) with power group, with RKE
The original engineering number was F81B-14B205-EP

Thanks.
My code reader says the current GEM is 14B205-EL, could that be the cause of the missing 4x4?

Would need the first part of the engineering number to see what it really fits

I will dig it out of the dashboard, hopefully the sticker is still intact.
The Software version is 1998-06-19, but i doubt that helps.
