The harness will connect two Spal Fans, with a 30/40 amp Relay and an inline fuse holder with fuse. Simply plug into your Spal Fans, and connect the power wire, ground wire and trigger wire for an easy wiring solution with your Fabless Slim Fan Set Up!

The kit also comes with the connectors you'll need, some zip ties and P-clamps to secure the harness to your fan shroud.

Install Notes

Power Wire (Red) - direct to battery/power source

Ground Wire (Black) - connect to chassis

Trigger Wire (Green) - fan switch to ground or toggle switch to ground if you want a manual override

We recommend attaching the relay with one of the fan bolts. However, a new hole can be drilled and tapped to mount the relay in a different location and we have supplied an additional piece of hardware for this.

Photos shown of harness installed are on a MK4 Fan Shroud, but the general routing and how the harness is fastened to the shroud will work in all of our Slim Fan applications.
