Recommended Adapter for 4-Way Round Trailer Connector on Motorhome

Question:

The trailer light outlet on my 95 motor home is 4-way round. One of the pins has the smaller .150? diameter, but the other three pins are closer to 3/16 diameter. What is that standard called? Heavy-duty 4-way? Will ADP001 have the 3 larger sockets?

The Custer Trailer Connector Adapter - 4-Way Round to 4-Way Flat # ADP001 will work for your 1995 motorhome with 4-Way round. The 4-Way round trailer wiring connections carry the same functions as the 4-Way flat trailer wiring connections they are just more heavy-duty, so this adapter will allow you to capture the functions you need for your trailer. The pins will fit the dimensions you gave as that is the traditional application for a trailer connector like # PK11404.
