Introducing the GML Industries Configurable Emergency Vehicle Junction Box

At GML Industries, we designed our Emergency Vehicle Junction Box to solve a problem that’s all too familiar across the emergency vehicle industry: every OEM, every truck, and every crew has slightly different needs — but most junction box solutions force you to choose between a rigid, one-size-fits-all design or a costly custom build from scratch.

Our answer is a common, configurable junction box platform built to adapt to your OEM’s specifications without starting from zero every time.

Built for Clarity and Configurability

From the start, the design priority was clear portrayal of parts and connections — no guesswork, no hidden wiring, no ambiguity for the technicians who service these boxes in the field. Combined with multi-configurability, this means the box can be adapted to a wide range of OEM truck and crew requirements while keeping the layout clean and easy to follow.

We also focused heavily on:

• Minimizing clutter — a clean internal layout that’s easier to inspect, troubleshoot, and maintain
• Maximizing maintainability and safety — accessible components and predictable routing reduce service time and risk
• Durability — built to hold up under the demands of emergency vehicle service life
• Price-conscious design — configurability without driving up cost unnecessarily

Nearly Ready, Right Out of the Box

Currently, our configurations come 85% properly configured out of the gate, with only minimal additional configuration necessary to equip your specific OEM truck and crew needs. That means faster turnaround for you, without sacrificing the precision your build requires.

What’s Coming Next

We’re not stopping at the junction box. Coming soon: a GML Industries Configurable Emergency Vehicle Console, built on the same philosophy — configurable to your OEM’s needs, without compromising on clarity, maintainability, or durability.

Together, the Junction Box and Console give GML Industries the ability to support the emergency vehicle industry end-to-end, configured to your customer’s needs from day one.

In-House Design, Built for Precision

Every configuration is backed by in-house design and custom assembly instructions, ensuring precision manufacturing with the speed your build schedule demands — while reducing the risk of manufacturing errors and ensuring dependable performance in the critical moments when first responders need it most.
