Losing track time to messy wiring?
Check out our custom ls7 Porsche 911 motorsport wiring harness
In racing, reliability is performance. A messy, hacked-together wiring harness can lead to endless gremlins—dropped signals, sensor failures, and wasted hours diagnosing problems in a rat’s nest of wires. That’s time not spent driving, tuning, or winning.
For this LS7-swapped Porsche 911, we built a brand-new motorsport wiring harness designed for simplicity, serviceability, and track reliability. The result? Faster diagnostics, rock-solid performance, and one less thing to worry about when the green flag drops.
