How to Install Flat 4 Trailer Wiring on a Wrangler

Save

Installing a flat-connector, four-blade trailer wiring harness to a Jeep Wrangler makes towing both simple and practical. The flat-connector four-pin hitch wiring conveys electrical signals from the Wrangler's wiring to the trailer's wiring, and runs all the lighting functions necessary to use a trailer on the road. The use of a dedicated hitch wiring kit involves only push-on/pull-off connections, so no tools are required. This is a simple and straightforward project which should take no more than thirty minutes.

Things You'll Need

  • Dedicated hitch wiring kit
  • Plastic zip ties
  • Obtain a dedicated hitch wiring kit for the Jeep Wrangler. They are available from most auto parts stores and Jeep dealerships.

  • Retract the plastic pins which hold the mudguard in position inside the driver's side rear wheel well. The plastic pins should retract with fingernail pressure only; if they have become seized slip a knife blade below their heads and flick them out. Remove the mudguard from the wheel well by allowing it to drop toward you.

  • Remove the terminal multi-block from the black plastic housing behind the rear light cluster. The terminal multi-block is a simple push-on/pull-off connector on the end of the wire to the light cluster. On some Wranglers there is factory-installed electrical insulation tape wrapped around the multi-block; this must be unwound before the multi-block can be pulled off.

  • Plug the hitch wiring kit into the back of the light cluster, then plug the terminal multi-block into the hitch wiring kit. Use new electrical insulation tape to cover the connections if any was removed earlier, then replace the mudguard and the plastic retaining pins.

  • Route the wire of the dedicated hitch wiring kit, properly called a pigtail, so the flat-connector four-pin hitch is in a location near your tow package. Secure the wire and the hitch in place with plastic zip ties.
