⚡ Custom Wiring Harness Design & Build
Precision-Built Harnesses for Street, Strip, and Track
At Moore Throttle Motorsports, every harness we build is designed with one goal in mind — reliability under pressure. Whether you’re wiring a street car, a Coyote-swapped Mustang, or a 2,000-horsepower race setup, our custom harnesses are handcrafted using mil-spec standards and motorsports-grade materials that deliver unmatched durability, organization, and performance.
🔧 What We Offer
Every build starts with a custom design tailored to your platform and goals.
We can build from scratch or rework an existing harness to meet your exact setup.
Common harness types we build:
- Complete engine harnesses (Coyote, LS, Mod Motor, Gen 3 Hemi, etc.)
- Standalone ECU integration (Holley, Haltech, FuelTech, MoTeC, etc.)
- Body & chassis harnesses for race and street cars
- Transmission harnesses (4R200, TH400, 6R80, 10R80, etc.)
- Power distribution and CAN bus integration
- PDM & switch panel wiring with clean labeling and service loops
Every wire is routed with intention — heat-rated, labeled, and secured for professional reliability and serviceability.
