Reliable Control for Dual High-Pressure Pump Setups

When you're adding serious fuel system upgrades like a dual high-pressure pump setup, having the right wiring harness is critical to making it all work together. The H&S Motorsports Dual High Pressure Pump Wiring Harness is designed specifically for trucks running dual pump kits, giving you the proper connections needed for smooth operation.

This harness isn’t just a plug-and-play accessory—it’s designed to be used in conjunction with aftermarket ECM tuning.

It gives your ECM the control it needs to manage both pumps efficiently, helping you get the most out of your fuel delivery system. Whether you’re building a competition truck or just pushing your street build to the next level, this harness helps ensure everything works together seamlessly. It’s a small but essential part of maximizing the performance and reliability of your dual pump setup.
