Professional Engine Wire Harness Manufacturing
OurPCB manufactures engine wire harnesses for automotive, industrial, and specialty engine applications. Our engine wiring solutions connect ECUs, sensors, fuel systems, and ignition components with materials rated for underhood temperatures and fluid exposure.
Our IATF 16949 certified manufacturing ensures automotive-grade quality for engine harnesses. We use high-temperature materials including XLPE, silicone, and PTFE insulated wires rated for engine bay conditions.
For sensor connections, we provide shielded circuits to protect sensitive signals from engine electrical noise. Our harnesses support temperature sensors, pressure transducers, position sensors, and oxygen sensors with proper shielding and grounding.
Whether you need OEM replacement harnesses, custom engine wiring for specialty applications, or rapid prototypes for development, we deliver engine harnesses that perform. Contact us to discuss your engine wiring requirements.
From the Case Bank
A European heavy-duty truck program required quoting for a long-lifecycle wire harness with grommets.
The initial RFQ contained drawing quality issues, forcing the customer to cancel the first quote and re-issue the RFQ with updated specifications, which compressed the quoting timeline and required rapid engineering re-evaluation.
Quickly adapted to the re-issued RFQ, re-evaluating the bill of materials and manufacturing process based on the corrected technical data package to ensure accurate costing for the long-term program.
Successfully re-quoted the project with accurate technical data, aligning with the customer's extended production timeline.
- SOP 2029
- EOP 2035
- 6-year production lifecycle
- 1 re-issued RFQ due to drawing errors
Engine Harness FAQ
Engine compartment harnesses typically require -40°C to +150°C ratings for general underhood use. Areas near exhaust manifolds or turbochargers may need higher ratings up to +200°C. We specify appropriate materials based on harness routing and application.
Yes, we can reverse-engineer and manufacture equivalent engine harnesses for OEM replacement or aftermarket applications. We use compatible connectors and wire specifications to ensure proper fit and function.
Yes, we manufacture fuel injector harnesses with appropriate wire gauges, connector types, and shielding for both port and direct injection systems. Our harnesses are designed for proper fuel injector operation and engine management compatibility.
We use automotive-grade wires including GXL, TXL, and SXL types with cross-linked polyethylene insulation. For high-temperature applications, we use silicone or PTFE insulated wires. Wire selection is based on current requirements and temperature exposure.
