The STS-1MSS Deluxe Sequential Harnesses have been specifically designed to work with all 1996 to 2004 Mustangs, regardless when they were built. These premium harnesses are a vast improvement over OEM and are made with chrome plated sockets that look super sweet inside the tail light lenses. They also include the proper grommet and clips, so you know the fit will be perfect!

All WebElectric Products Pre-wired Harnesses are Plug-N-Play, which means there is no cutting, splicing or harness modifications of any kind. You simply unplug the old harnesses, swap the light bulbs and plug in the new harnesses to have sequential turn signals in about half an hour.
