High-Power Automotive Controlfor when regular switches won’t work
Your high-power solution for when regular switches can’t handle high-current loads. Adding relays can become a complicated and messy project — our fused relay boxes provide centralized control and protection with minimal wiring involved. Ideal for all automotive devices such as spotlights, motors, pumps, and fans.
Wiring is made easy. Each automotive relay box comes with a red main feeder cable and labeled screw terminals. Use the Installation Manual and wiring diagrams to help connect your power source, switches, and loads. It’s that easy.
Quality is Guaranteed. Every automotive relay box is tested, with relays rated 40A at 12 volts to ensure optimal reliability come race time. What’s more, our relay boxes are built with GXL high temperature wire, and with no-nonsense screw terminal strips for reliable input and output wiring.

Connect the red main feeder conductor to the car starter’s battery power terminal. Then, install the supplied main fuse and holder in the main feeder conductor between the starter and the power stud found inside the panel.
Switches & Grounds
Install a ground wire between the relay panel and the auto chassis. Then, connect the control circuit terminal to your switch inputs, with switch outputs connected to the appropriate screw terminals.
Connect your loads to the appropriate screw terminals. Ground your loads. See the 3, 4, 6, and 8 relay module diagrams above.
