We offer trailer connectors, sockets and plugs in many connector formats that you can view in the linked article on trailer wiring. I also linked our main page for all 4-pin round connectors such as vehicle-side female socket # RM-910030-1 and trailer-side male plug # PK11402. We also have a kit with both, part # RM-910030-4 from Roadmaster.

You'll want to be sure to wire the new connectors based on each wire's function, not by its wiring insulation color as this is not always consistent.
