To wire in a 4-way you'd want the part # 18252 which comes with quick splices that you'd use to tap into the wiring of the first trailer. You have standard 4-way trailer wiring colors correct but your trailer may use different colors so you'd basically just have to check out the wiring that runs to all the lights of your trailer assemblies so that use the correct circuits. The # 18252 comes with a circuit tester to so you can test the wiring too and be sure.
