PANDEMIC would like to introduce our revised Jeep Wrangler JK | JKU taillight adapter wiring harness. This harness allows for any standard Stop-Turn-Tail (STT) taillight to be wired quickly and easily. The harness features the Jeep JK OEM Female plug on one end that plugs directly into the Jeep's OEM chassis harness. On the other end it features a 3-way plug for the industry standard STT lights whether it be LED or incandescent. The fourth wire (green) is the lead for the chassis reverse/backup light. We now have a 5th wire that is the ground lead in the same gauge as the reverse light lead to make for a cleaner install without the use of wire taps to connect a reverse light. This harness will allow for any JK owner to have an almost complete plug-n-play harness and will make the wiring issues a thing of the past! The new adapter harness is common sense addition to any conversion on the market that requires a light conversion. These will work with ALL manufacturers 4" LED lights and any reverse light. Manufacturers can offer this upgrade with their kits to help enhance the installation experience. No more chopping up the factory harness and matching color codes. Save time and save money with this simple, inexpensive upgrade from PANDEMIC.
