Expert Reply:
We can definitely help Wayne but you'll need to first install a 4-way like with the Curt part # C59236 which is a universal style 4-way that fits your Sprinter. To then convert to a 7-way you'd just need the part # 37185 if all you need is trailer lighting.
If you have trailer brakes as well you'd instead of the 37185 need the part # ETBC7 and a brake controller like our very popular P2 part # 90885 and you'd be set.
