⚡ Classic & Muscle Car Wiring Services
Old School Style. Modern Reliability.
Vintage muscle cars are timeless — but their factory wiring? Not so much. Brittle insulation, poor grounds, and corroded connections can cause endless electrical headaches. At Moore Throttle Motorsports, we completely rewire classic cars using American Autowire and Painless Performance harnesses — installed better than factory.
Our wiring upgrades bring your classic into the modern age with cleaner routing, reliable power delivery, and labeled serviceable circuits that’ll last for decades.
🔧 What We Offer
We specialize in full or partial rewiring for classic and custom vehicles.
Common services include:
- Complete rewire using American Autowire or Painless harness systems
- Factory harness replacement and cleanup
- Engine bay and dash wiring rework
- Fuse box and relay panel installation or relocation
- Ground and power distribution optimization
- Aftermarket gauge and switch wiring
- Lighting upgrades (LED conversions, headlight relays, etc.)
- Alternator, starter, and ignition circuit repairs
- Accessory and stereo power integration
- Hidden wiring and custom loom options
Every connection is soldered, crimped, and sealed to outlast OEM — while preserving the car’s originality and serviceability.
⚙️ Our Approach
We treat every classic car like it’s getting a race-grade electrical system.
Even though these cars didn’t leave the factory with modern standards, that doesn’t mean they can’t have them now.
Our process includes:
- Harness layout & planning — tailored to your car’s options and upgrades.
- Professional installation — proper routing, support, and strain relief.
- Ground-up verification — continuity, voltage drop, and load testing.
- Customization options — hidden fuse boxes, labeled circuits, or added accessories.
We can integrate modern upgrades like electric fans, EFI conversions, or even standalone ECUs — all tied into a clean, serviceable harness.
