LT1 & LS1 Connectors
 
Single High Speed Fan
Custom made for your application
Weatherpack construction with HD wiring
Dual 40 amp rated military spec relay
Direct battery power connection removes excessive loads from factory wiring, relays or fusible links
Improved voltage supply = improved air flow
All connections are crimped and sealed like an OEM connection -- not soldered to cause early vibration failure
Up to 12 feet of cable relays to ECU or switch control for custom applications
6' cable from Relay to Fan
Supplied with aftermarket connectors for auxiliary fans
Requires ECM reprogramming when vehicle did not originally come with electric fans -- can be manually switched, or switched using a thermal switch in radiator
Proper GM programming will:
Run each fan individually. Can be programmed for Single fan cooling. On and off temperatures of your choice
Run fans with ECM AC request signal -- not the clutch signal. Therefore the fan doesn't cycle on and off with the fan clutch, but uses the pressure signal from the AC system to correctly run the fan. OEM pins, nothing clipped to harness wiring, simple, reliable installation
