Hey Andrew, for your 1992 Dodge W250 we only have plug and play 4-way kits available like the Curt # C55317. This is due to the age of the truck but we can still help. To convert this to a 7-way you'd just need the part # 37185 if the trailer does not have any brakes or the part # ETBC7 plus a brake controller like the # 90885 for if the trailer does have brakes as this comes with the needing wiring and connections to install a 7-way as well the brake controller.
What are you towing?
