NEED A PROJECT WIRED?

Vintage, hot rod, race car, or custom — it doesn’t matter. You have a project. Let’s get to work.

We start with one list.


In person or on the phone, we walk the same checklist so nothing gets missed:

  • Vehicle and powertrain

  • Engine management (EFI or carb)

  • Lighting

  • Accessories — HVAC, radio, power windows, Dakota Digital, and anything else on the car

  • Install style — classic cloth loom, mesh throughout, or mesh only where it counts

  • Budget

Those details tell us what wire, connectors, and loom belong on the car. We stay in touch throughout the estimate process. Once cost and delivery are locked in, the build starts.

Now, the custom build:

  1. Strip and access. Old wiring comes out. Interior pieces come apart so we can reach the tight spots.

  2. Install the new hardware. Gauges, lights, horn, HVAC, and the rest of the aftermarket list go in first.

  3. Template the car. We measure the vehicle so every run is the right length before a single wire is cut.

  4. Build the harness on the bench. The template comes to the bench. Every inch of harness is built to the car and its parts. Connectors and loom go on here.

  5. Install. The harness goes in the vehicle. Fuse boxes get mounted. Connections get made.

Most full harness jobs take 2–6 weeks, depending on how deep the project is.

When it’s done, the car is ready for summer driving: hot engine bays, heat soak, high-current fans, A/C, and a harness built to carry the load with a Lifetime warranty.
