How To Tow Trailer with Separate Stop/Turn Signals Using a 2018 Mazda CX-5


How to get separate turn signal /brake/running lights connected to car lights. Wire colors black, red, green yellow. 2018 Mazda cx5

In order to tow a trailer using separate brake and turn signal circuits with your 2018 Mazda CX-5 you will first need a standard 4-way trailer wiring harness, the Curt T-Connector Vehicle Wiring Harness part # C56377 which is plug and play. Then, in order to attach the trailer to this connector you will need to install a converter in between the trailer lights and trailer side trailer connector, the Vehicle to Vehicle Tail Light Converter part # 118158 along with a trailer side 4-way, the Hopkins Endurance Easy-Pull Harness part # HM38134.

If the trailer has brakes then you will also need the Universal Installation Kit for Trailer Brake Controller part # ETBC7. The Hopkins Endurance Easy-Pull Harness part # HM38134 would then be swapped out for the Bargman 7-Pole Round Connector part # 54-67-525.

Please note, the lights on the trailer must be combined as there really is not a good way to tow with separate trailer tail lights using US trailer connectors which is all that we offer.
