Classic Car Wiring & Harnesses
TOP END INDUSTRIES
Clean, serviceable wiring for classic vehicles
Electrical problems can turn a good car into a car you do not trust. Top End Industries provides wiring-harness installation and electrical work for classic cars, hot rods, street/strip builds, restomods, and engine-swapped vehicles in East Tennessee.
Whether the vehicle needs a complete rewire or one stubborn circuit diagnosed, the goal is the same: safe routing, logical protection, reliable connections, and a system that can be serviced later.

Harness selection starts with the whole car
The right harness depends on more than the year on the title. We look at the engine and ignition, charging system, gauges, lighting, fuel system, cooling fans, accessories, and future plans before the project is scoped.
What to include with your inquiry
- Year, make, and model
- Engine, transmission, ignition, and fuel-system details
- Current symptoms or the reason for the rewire
- The harness or electrical parts already purchased, if any
- Photos of the engine bay, dash, fuse panel, and existing wiring
- Your location and preferred timeline
