Here at Tick, we developed this harness to allow you to add 2005+ GM/Chevrolet ECM controlled Electric Cooling Fans to the 1999-2002 GMT800 platform Trucks and SUV’s, which includes the following:
GMC Yukon XL
The unit is modeled after the stock 05+ schematics, allowing dual speeds (determined on ECM settings) as well as an additional, selectable speed control integrated in with the AC system. This is a fully sealed, ECM Controlled, watertight unit with a very sleek installation and minimal visible wires. Works on the 1500, 2500, 3500 series Silverado, Sierra, Tahoe, Suburban, Yukon, Denali, Avalanche, 4.8L 5.3L 6.0L 8.1L or any LS Swap with the 0411 ECM. This is NOT direct plug and play system for 4.3L or 6.6L Duramax.
Instructions included as well as friendly, professional tech support from our staff here at Tick Performance.
