Corona, CA · Quoted against your car
Motorsports wiring
Standalone ECU harnesses, swap wiring, sensors and power distribution — built here, then calibrated on our hub dyno. Tell us the car and the plan; we quote it against the car, not a guess.
Mon–Fri 9:00am–6:00pm
Wiring that the tune can trust
A calibration is only as good as the signals it reads. A sensor on a noisy ground, a crank trigger with a weak shield or an injector harness with one bad pin shows up on the dyno as a fault nobody can tune out. We wire it so the data is clean, then we tune it on the same car, so one shop owns both halves of the job.
The proof of a harness is the car running right under load, with the dyno sheet to show it.
- Standalone ECU installs: Holley, Haltech, Link, MoTeC, Emtron, FuelTech and others
- Engine swap harnesses, including finishing a plug-and-play harness to your chassis
- Added sensors: fuel and oil pressure, ethanol content, wideband, EGT, boost
- Power distribution modules, switch panels and fuse and relay layouts
- Dash and data logger wiring
How it is priced
Wiring is shop labor at $265 an hour, quoted against the car before any work starts. Parts are priced separately, and the calibration is priced on its own page. Two harnesses that look the same on paper can be a day apart in a real chassis, so we do not publish a single figure that would be wrong for most cars.

Before you ask
Questions people ask
- Can you finish a plug-and-play harness I already bought?
- Yes. Most "plug-and-play" harnesses still need power, grounds, a fuel pump feed and chassis connections. Tell us which harness it is.
- How much does it cost?
- Shop labor is $265 an hour, quoted against your car before work starts. Parts and the calibration are separate.
- Will a tuned or swapped car pass a California smog check?
- No, not on that basis. Wiring and tuning for power are for off-road and competition use. We say so before you book.
