Recommendation For Connecting 2004 Ford Ranger Factory Tow Package To Trailer With LED Lights  


Need help with trailer wiring. My 2004 Ranger has a factory tow option which includes a 3 wire plus ground flat plug already installed. My trailer tail lights are LED and have three wires each-white ground and a black and a red. I think I need a converter that would plug into my trucks factory flat plug and then plug into my trailers wiring. Can you recommend the connection I need? How many wires need to go to my trailer?


Helpful Expert Reply:

Based on the information you sent, it sounds like you do not need a converter and only need a regular trailer side 4-way harness. I recommend the Hopkins Endurance 4-Way Flat Trailer Connector, Item # HM48110, for your 2004 Ranger and trailer.

Based on your information, it sounds like the white is ground, the black is tail lights, and red is brake/turn signal for each light. When you connect these to Item # HM48110, the yellow wire will be left turn and brake, the green wire will be right turn and brake, and the brown wire will be the tail lights.

Additional information and videos attached.
