Make sure your GMC S15 performs the way you want it to by keeping the fuel system wiring components in top shape. With high-quality wire, cable and related components from StockWise Auto, your vehicle has the power to get you where you need to go every time. Dependable wiring harnesses for a wide variety of air and fuel delivery components ensure top fuel efficiency whether you're cruising the highway or driving around town.


If you notice difficulty starting your GMC S15, poor gas mileage, engine stalling issues or lack of power when trying to pass other vehicles on the highway, the problem may be faulty fuel system wires. Don't get stranded far from home. Replace problem wiring with new wiring harnesses instead, and enjoy every drive.
