Switches. Relays. And Everything in Between.
Featured Products
Automotive Switch Panels
We build only the most reliable and popular show car and racing switch panels — with premium rockers or toggles — which are designed to control 12 volt lighting, fully-resistive loads, and relays that operate motor loads.
MGI’s unique online experience allows you to customize your switch panel with ease.
Choose the number of switches, their colors, a main fuse size, an optional enclosure — and much more.
Automotive Relay Panels
An MGI Relay Panel gives you dependable control over your high-current electric accessories. We offer relay harnesses for cost-conscious projects, SPST relay boxes for standard automotive applications, and performance SPDT relay panels for maximum versatility.
When it comes to your race car, show boat, or truck, there’s no substitute for high-quality relays and fuses.
Automotive Fuse Panels
In most vehicles, OEM fuse panels are designed to operate standard lighting, ignition, and resistive loads – not high-performance electrical pump or fan loads. That’s where MGI steps in.
Our standard fuse panels come with labeled terminals for easy connection to popular OEM devices, while our racing fuse boxes are designed for relay-driven, high-power accessories.
