Custom Wiring Harnesses for Every Industry

Every industry has its own set of environmental challenges, connector standards, and reliability requirements. We build harnesses that meet the specific demands of your application, whether it lives under a hood, in the ocean, or on a factory floor.

A wiring harness for a race car is nothing like one for a fishing boat or a CNC machine. The materials, connectors, wire types, and assembly methods change depending on what the harness needs to survive — heat, vibration, salt water, cutting fluids, or all of the above. We design and build custom harnesses for each of these environments using the right connector families, wire insulation types, and protection methods for the job.

Automotive / Hot Rod

Custom wiring for street rods, restomods, pro-touring builds, and classic car restorations where the factory harness is either missing, rotted, or completely inadequate for the new drivetrain and accessories. Common projects include LS and Coyote engine swaps into classic trucks and muscle cars, full chassis rewires to replace brittle cloth-wrapped harnesses, and integration of modern EFI, electronic overdrive transmissions, and aftermarket gauge clusters. These builds often combine components from multiple decades and manufacturers, creating wiring challenges that no off-the-shelf harness can solve.

Motorsport / Racing

Lightweight, mil-spec wiring for any form of competition where reliability, weight savings, and quick serviceability are non-negotiable. Built with Tefzel wire, concentric twisting, and aerospace connectors. Applications range from endurance road racing and time attack cars to drag cars running standalone engine management, rally cars needing waterproof harnesses that survive stage conditions, and oval track vehicles with extensive data logging. The wiring in a race car is a safety-critical system — an intermittent connection can cause a misfire at 8,000 RPM or disable a fire suppression system when it matters most.

EV Conversion

Wiring for converting internal combustion vehicles to electric drive, including high-voltage battery pack wiring, BMS integration, inverter connections, and charging system harnesses. Typical conversion projects include classic cars and trucks receiving AC or DC motor swaps, Porsche 911s and VW buses getting modern lithium packs, and fleet vehicles like vans and school buses being electrified for zero-emission operation. Each conversion requires careful integration between the new electric drivetrain and the vehicle's existing body electronics, lighting, HVAC, and instrument cluster.

Agricultural / Farm Equipment

Rugged wiring for tractors, combines, sprayers, planters, and implements that operate year-round in dust, mud, chemicals, and extreme temperatures. Applications include rewiring older tractors to add precision agriculture capabilities, building custom harnesses for specialty implements like strip-till rigs and seed tenders, and integrating aftermarket rate controllers and section control systems on sprayers. Farm equipment wiring must work reliably from sub-zero winter mornings through 100-degree summer harvest days, often while coated in a layer of crop dust and chemical residue.

Marine

Corrosion-resistant wiring for boats, yachts, and marine engines using tinned copper, sealed connectors, and ABYC-compliant construction to survive salt water, humidity, and years of UV exposure. Projects range from complete rewires of aging cabin cruisers and sailboats to engine harnesses for repowered sportfishing boats, custom helm panel wiring for center consoles, and accessory harnesses for livewells, trim tabs, trolling motors, and underwater lights. Marine electrical failures are more than an inconvenience — they can leave a vessel without navigation, communication, or bilge pumps in open water.

Industrial Machinery

Wiring for CNC machines, packaging lines, conveyor systems, and manufacturing equipment where uptime, safety compliance, and EMI management are critical to operations. Typical projects include building harnesses for custom machine builders (OEMs) who need repeatable production-quality looms, retrofitting older machines with new controls and drives, and wiring up automated cells that combine multiple machines, robots, and inspection stations into a coordinated system. The cost of a wiring-related failure in production is measured in thousands of dollars per hour of downtime, making harness quality a direct financial concern.

Robotics / Automation

Flexible, high-cycle wiring for robotic arms, automated guided vehicles, collaborative robots, and end-of-arm tooling where cables must survive millions of bend cycles in tight spaces. Applications include six-axis industrial robots performing welding, painting, and material handling, SCARA robots in electronics assembly, collaborative robots (cobots) working alongside humans on assembly lines, and mobile platforms like AGVs and AMRs navigating warehouse floors. A broken conductor inside a robot dress pack can halt an entire production line, making cable longevity and serviceability essential design requirements.

Aerospace / UAV

Ultra-lightweight, high-reliability wiring for drones, unmanned aerial vehicles, experimental aircraft, and aerospace subsystems where failure is not an option and every gram counts. Projects include multi-rotor drones used for aerial survey, inspection, and delivery, fixed-wing UAVs for mapping and agriculture, experimental and homebuilt aircraft with custom avionics stacks, and high-altitude or long-endurance platforms that push the limits of weight and power budgets. Every connection point is a potential failure mode at altitude, so harness design and build quality directly affect mission success and airworthiness.
