No spam, no pressure. One call from a real builder — not a sales rep.
Most classic electrical trouble comes down to one thing: decades-old wiring that was never built for modern loads. We start at the source — a proper fuse and relay panel — and build every circuit out from there, labeled and diagrammed.
From a complete custom harness to EFI and digital gauges, we build electrical systems that are clean, hidden, and dead reliable.
We strip out old, dangerous factory wiring and install complete, bumper-to-bumper modern chassis harnesses — engineered for your build and labeled for life.
Expert install, plumbing, tuning, and troubleshooting of Holley electronic fuel injection — carb headaches gone.
Modern digital/analog hybrid instrument clusters, integrated accurately over clean CAN-bus data.
We tuck and route every wire away from heat sources and moving parts — for a clean, show-quality engine bay with nothing exposed, melted, or tangled.
Old wiring doesn't just look bad — it strands you. Here's what changes when we re-engineer your electrical system.
| Old / Factory Wiring | StreetWorks Harness | |
|---|---|---|
| Wire & insulation | ✕Cracked, brittle, unsafe | ✓Fresh, heat-rated wire |
| Circuit protection | ✕Old glass fuses, overloaded | ✓Modern fuse & relay panel |
| Diagnosis | ✕Guesswork & gremlins | ✓Labeled, diagrammed circuits |
| Fuel delivery | ✕Finicky carburetor | ✓Holley EFI-ready |
| Instrumentation | ✕Failing factory clocks | ✓Dakota Digital accuracy |
| Appearance | ✕Cluttered & exposed | ✓Hidden, show-quality routing |
| Reliability | ✕Random no-starts | ✓Start-every-time confidence |
Take a cluttered classic engine bay, hide every wire, drop in a Holley Terminator EFI ECU, and connect it to a crisp Dakota Digital cluster with clean CAN-bus data modules. That's a StreetWorks build — modern data, zero clutter.
A look at the kind of electrical builds we turn out — swap in your photos of harnesses, engine bays, and digital dashes.
Bad wiring ruins great builds. We treat your electrical system like the critical system it is — engineered, documented, and warranty-backed.
Every circuit documented, so future service is simple — not a mystery.
Itemized scope and cost before any wire is cut. No surprise invoices.
Hidden, tucked, and protected from heat and moving parts.
Every harness & install is covered by a written parts-and-labor warranty.
Every harness and install is quoted in writing, diagrammed, and backed by a written parts-and-labor warranty. No work starts without your approval, and your car leaves labeled, tested, and gremlin-free — not a bundle of loose ends.
