Package including:
1x Silverado Freestanding Electric Fan Wire Harness

Describe:
The wiring harness includes a custom relay and circuit breaker installed in the original enclosure of the fuse
box (see photo).

Installation is simple. Simply mount the relay hub on the fuse box cover using the hardware provided, then
connect the power wire, ground wire, two ECM control wires, and plug the two fan plugs into a set of fan truck
electric GM 2005 or later.

When FAN 1 starts correctly, both fans will be at low speed, and when both FAN 1 and FAN 2 are started, both
fans will be on at high speed.

OEM fan assemblies are only available for 34" wide radiators. If your truck has radiators of different widths,
then you should also upgrade your radiators.

NOTE: Newer Silverado and Sierra trucks and SUVs with gasoline engines can control the electric fans via their
original ECM, but you must have someone with a "tuner" turn them on for you. Product is not suitable for diesel
engine applications.
