How To Wire Ford Focus For Trailer Lights

Want to know how to wire your Ford Focus for trailer lights? You’ve come to the right place. If your Ford Focus has a Class I hitch and you’re interested in putting it to good use, then you’ll have to have it wired for trailer lights. A trailer light wiring harness connects your car’s brake and tail lights to the trailer, insuring safe operation. Installing a wiring harness for trailer lighting is an easy task that can be done in under an hour, plus it doesn’t take many tools to get the job done. The following describes how you can successfully wire up your Ford Focus for trailer lights.

What you’ll need:

  • Phillips head and flat head screwdriver
  • Pliers
  1. Remove the tail lights. Gain access to the tail light housing by pulling back the carpeting covering the housing. Remove the plastic wingnuts and slide the tail lights out of the car, leaving the wiring intact.
  2. Install the wiring for the trailer lights. Behind each tail light are plastic connectors that must be separated in order to install the trailer light wiring.  Separate these connectors then thread the trailer wiring connectors through the car body behind each tail light. Insert the connectors into the car’s wiring harness, in accordance with the instructions for your trailer light wiring.
  3. Reattach the tail lights. Push the tail lights back into position and re-secure them with the plastic wingnuts. Run the trailer wiring under the carpeting in the trunk. The connector will extend from between the trunk lid and bumper when in use.
