On 3 Performance 1999 – 2006 Dual Electric Fan Upgrade Wiring Harness for ECU Control
This is the new harness that many customers have been asking about. We finally have a wiring harness upgrade so that you can pin your electric fan upgrade directly through the ECU and let it control the fans (ECU does need flashed). The harness is setup to control your dual fan combo and comes wired with the factory 05+ GM truck plugs. If you buy our fan kit along with this, the correct plugs will come with your fan kit so its a quick and easy install as well. By running this harness, it will make for a clean, factory install and never have to worry about triggering your fans or using those horrible probe thermostats that never work properly. This is almost a must when upgrading your truck to electric fans. Check out our dual truck fan as well to make a package deal!
