Jeep Conversion Integration

Many standalone harnesses are built generically. This offering is selected specifically to support the conversion workflow Novak customers expect: clean routing, practical branch lengths, and a simplified integration mindset for Jeep installs.

PCM / ECM Notes

• Harness and ECM must be compatible for your engine generation and operating strategy.
• Transmission selection impacts wiring and ECM requirements (especially across 4L and 6L families).
• VVT selection must match the engine’s actual hardware configuration.
• Throttle pedal selection must match the pedal you will run in the Jeep (or the donor pedal you already have).

If you need help confirming your ECM/harness match, contact our sales team and we’ll help you get it right before you order.

Important Notes

• Emissions & O2 sensors: Your final configuration must comply with your local jurisdiction.
• Do not modify harness circuits unless you fully understand the effect on reliability and warranty coverage.
• Lead times: Build/ship timing can vary seasonally. If your project is schedule-driven, contact us for current timing.

Support

If you’re not certain which option set matches your engine, call our sales team before ordering. A few minutes confirming transmission type, VVT status, throttle pedal style, MAF style, alternator plug, and MAP sensor style prevents delays and rework.
