Hey Michael, if the trailer doesn't have brakes that you need to operate all you need is the part # 37185 to convert your 4-way to a 7-way. If you do need to operate brakes you'd instead need the part # ETBC7 with a brake controller like the P3 part # 90195 and you'd be set.

Hey Michael, how did things go with the adapter for your 4-way to 7-way wiring setup? Did the 37185 or the ETBC7 kit end up being the right fit for your trailer? Your update could make it easier for others working through the same wiring change.
