I can offer you a solution, though a 7-round to 4-round adapter is not available. What you will need to do is create your own by wiring a 7-round trailer end connector, # PK11700, and 4-round vehicle end connector, # RM-910030-1. I recommend going with the 14 gauge, Deka Jacketed 4-Wire, # DW04923-1, which is available per foot so you can get the amount you need.

If you have an RV-style connector (which is often referred to as a 7-round), then the part you would be looking for is the Hopkins Endurance Adapter, # HM47043.

I have added links to video reviews of these products, as well as a help article on wiring which you may find useful.
