Custom wiring harnesses
Engine, chassis, and dash harnesses built to your car and your layout: engine swaps, EFI conversions, and full race looms, labeled and documented.
// Wiring harnesses & automotive electronics
Wired right.
Wired right.
Built to race.
Ranch Racing builds custom wiring harnesses, designs purpose-built electronics, and sorts out electrical gremlins for classic cars and race cars, without the boutique price tag.
// Services
What we build
From a single sub-harness to a full chassis loom and the electronics that plug into it.
Custom PCB & electronics design
Purpose-built control boards, sensor interfaces, and microcontroller firmware for the jobs off-the-shelf parts don't cover.
Repair & diagnostics
Intermittent faults, melted connectors, mystery drains, and previous-owner wiring. We trace it, fix it properly, and tell you what we found.
Low-cost electronics for classic & race cars
Affordable gauges, controllers, and add-on modules designed for vintage and track cars. Modern function, sensible price.
// Why Ranch Racing
Built like it's going on our own car
A harness is the nervous system of the car. When it's done right you never think about it again. That's the goal on every job.
Talk about your build- Motorsport-grade materialsProper wire, sealed connectors, and protective sleeving where it matters.
- Documented & labeledEvery circuit labeled, with a wiring diagram you can actually use later.
- Engineering, not guessworkCircuits sized for the load, fused correctly, and routed for heat and vibration.
- Honest pricingClassic and grassroots racing budgets are real. We design for them.
// Process
How a job runs
Tell us the build
Car, engine, ECU, what's working and what isn't. Photos help.
Plan & quote
We scope the circuits, components, and layout, then send a clear quote.
Build & test
Built on the bench, continuity-checked, and tested before it ships.
Install & support
Documentation goes with it, and we're here if questions come up.
