This harness is a direct plug-n-play harness to install later GM Truck electric factory fans. This allows you to control the fans through the ECU(ECU Flash Required). The harness is pre-pinned to install directly into the ECU connector. No need for cutting and splicing! By running this harness, it will make for a clean, factory install and you'll never have to worry about triggering your electric fans using those horrible probe thermostats that never work properly.
If you need even more cooling power, check out our DUAL ELECTRIC FAN UPGRADE. If buying our fans, you can add this harness as an option and we'll include the correct connectors at no charge.
