Product Description
1999-2006 Electric Dual Fan Upgrade Wiring Harness ECU
Replaces 7L5533A226T
You can use this harness to 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 05+ GM truck plugs. With this harness, you don't have to worry about triggering your fans or using those horrible probe thermostats that never work properly. This is a must when upgrading your truck to electric fans.

Shipping was quick, came in as pictured and seems to be built really well.
I will come back after installation to give my thoughts, but I’m 100% this product will work great
