This all new Harness allows you to plug in and adapt a C7 Or 6th gen Camaro/ZL1  brushless fan into your C5! 

The C5 uses a unique 3 relay switching fan control, for single fan use, dual fan low speed (6v) and dual fan high speed (12v) to alter fan speed. This was cool in the 80s when this car was developed!

Enter the C7 brushless fan. It absolutely flows 3x more air than the OEM brushed dual fan configuration.  But how do you control it? The C7 (600w 16" blade) and the Camaro ZL1 (800w 18" blade) fans are PWM controlled at 128hz.  

Our semi autistic and creative design team  drummed up a printed circuit board that plugs in, converts everything to PWM, and the OEM control strategy still functions!

Low speed= 25% PWM duty cycle

Medium speed= 50% duty cycle

High Speed= 80% duty cycle

Why we think this is the greatest fan combo for the C5 ever:

• Modern fan technology meets old school
• separate loom for fan control and power, 80amp fused power cable direct to fuse block
• plug and play configuration, no cutting of wires
• AC Fan control function still OEM
• C7 fan is smaller than OEM
• ZL1 fan is larger, to help keep cool even the most demanding engine/supercharger combos
