Chase Bays Dual Fan Relay Wiring Harness w/180 Degree Thermoswitch

Chase Bay wanted to make an all-in-one solution that was super easy to install and looked incredible. There are dozens of other fan relay wiring kit solutions, but this stands far from the crowd. Other kits are two pre-crimped relays, some butt connectors, and a handful of zip-tied wire. Not cool. 

The installation couldn't be easier. The wires labeled "thermosw" run to the included 1/8 NPT thermo-switch that you will install on the post-thermostat lower side of your radiator. Any Chase Bays Tucked Radiator purchased from 2018 onward will have (2) 1/8 NPT ports on the radiator. If you're installing this on another radiator, all you need is a 1/8 NPT female weld-on, which can be purchased from the Chase Bay site (CB-18-FWLD). The wires labeled "fans" go to your fans (duh!). Then, you just ground the "GND" wire to a clean surface with a steel or stainless steel non-painted bolt.

The wire labeled "battery" is the main power wire. It can be connected in two different ways. It is already fused in the fuse box so it can be connected to the battery, alternator, or starter. If you do this, the fans will stay on until the coolant is below 180º F. Even after the car is turned off. If you don't want it to be this way, just hook the battery lead up to a switched 12v source. (Disclaimer: We're not sure where that is on your particular chassis and can't assist you in finding it)
