Preterminated Universal Engine Harnesses


Our preterminated universal engine harnesses are the perfect solution for engine swaps, race applications, or unique builds that need a comprehensive, ready-to-run engine harness solution.

We begin with an unterminated harnesses and pre-configure its dimensions, endpoints, and routing for the most common and popular use cases. Flexibility and customization is retained by usage of breakout connectors with associated sub-harnesses to suit whatever you choose. 


All unused, remaining ECU inputs and outputs are terminated into spare connectors for easy expansion in the future.

If your vehicle already has OEM wiring in place, and you just want to convert to a standalone engine management system, please consider our Stock ECU Harness Adapter solutions which are typically a better, more cost-effective option.
