If you've purchased one of our radiator kits with a single fan, then this is the fan harness you need to wire your new cooling fan up without headaches and reliability issues.
Why 10 gauge wire? Well, did you know dropping the fan voltage from 13.8v to 12.0v will cut the fan CFM output by over 20%? The quickest way to drop the fan voltage between the battery and the fan is to use cheap wiring. All of our fans need 10 gauge wire to get the necessary amps to the fans without causing excessive voltage drop.
Next on our list of must-haves in our killer harness kit is the a sealed 40 amp relay, no Chinese $.75 relay that's going to crap out in a few weeks. In addition, the relay has a Delphi Metripack sealed socket connector. If you're not familiar with Metripack connectors, they are OEM connectors used on just about every GM vehicle on the road. They are sealed to keep moisture out and ensure the relay lasts essentially forever. We're so sure of that the entire kit has a lifetime warranty on it.
To eliminate the problems, we use a 10 gauge fuse holder made with virgin PA-66 material using Delphi sealed connectors for both the wires and the fuse. This ensures you won't pull over on the side of the road and find your fuse holder melted on a hot day or a long road trip.
To recap, our dual fan harnes includes everything you need to install your new electric fan setup:
- Dual fan harness with 10 gauge wire, sealed 40 amp relays and sealed relay holders
- Engineered brass 3/8" NPT 187F temperature switch
- Installation kit including tie wraps, crimp connectors and mounting screws
- Lifetime warranty
- Sealed Delphi Metripack connectors that connect directy into all of our cooling fans
