Pre-Wired Relay Box with Built-In Fuses
An MGI relay box can control high-current car accessories that regular switches can’t handle. Have electric motors, spotlights, or high-current resistive loads? A relay box will do the trick. Comes with fused relays, a main fuse, and main feeder conductor.
Features
- Lightweight and compact aluminum construction
- No messy wiring — the SPST relays are pre-wired and ready to go
- Every individual relay allows for negative switching
- Proudly designed and assembled in North America
FUSED RELAYS WITH LEDS
Innovative relays with built-in fuses greatly reduces the amount of wiring needed. SPST relays are rated 40A at 12vDC, with smart LED fuses that glow when blown. What’s more, each relay and fuse can be easily replaced if needed.
EASY-TO-WIRE SCREW TERMINALS
High-quality barrier screw terminals makes wiring quick and easy, especially with fork / spade connectors. Each screw is clearly numbered – simply use the included wiring diagram to make your connections.
PRE-WIRED AND READY TO USE
MGI SpeedWare relay boxes are designed to reduce custom wiring as much as possible – that’s why our boxes are pre-wired and ready to go. All you need to do is connect a power source, switches and loads to the appropriate screw terminal.
Modular Relay Panel Wiring Diagramshow to install 3, 4, 6, and 8 relay modules
STEP 1
Battery Power
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.
STEP 2
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.
STEP 3
Outgoing loads
Connect your loads to the appropriate screw terminals. Ground your loads. See the 3, 4, 6, and 8 relay module diagrams above.
