Description

Part #: DD8784

Overview Upgrade your vehicles setup with the Diode Dynamics D-Switch! This advanced 8-channel switch panel gives you full control over any 12V accessory with four 30A and four 15A outputs, delivering serious power with unrivaled customization. Dedicated Backlight Channel. Unlike other 8-button controllers, the D-Switch includes a 9th button for the dedicated backlight bus bar, providing eight extra outputs for accent lighting. Activate all backlit accessories with a single press, freeing up main outputs for other functions. Dynamic Channel Assignment. Unlike one-to-one switch panels, the D-Switch allows multiple output channels per button, giving you complete control over your setup. You can also assign multiple functions of an output to different buttons, such as configuring one button for flashing and another for full power of the same light. Fast, Responsive Bluetooth App. Control and configure settings using the Bluetooth app for iOS and Android, which delivers instant response, no lag, and seamless programming. OEM Signal Integration. Three trigger wires are included to automatically activate your outputs with vehicle signals such as high beams, fog lights, or reverse lights. The ignition wire powers the controller when the vehicle starts, shutting it down automatically when turned off. The Night Mode wire adjusts output settings and controller brightness for low-light conditions. Solid-State, Durable Design. The D-Switch is built to withstand the toughest conditions, with a solid-state design and an IP67-rated aluminum heatsink for superior heat dissipation. No mechanical relays to wear out or physical fuses to replace! Whether for off-road lighting or other 12V accessories, the D-Switch offers unmatched power, customization, and reliability.

Program and control multiple lights with one button. Dedicated button and bus connector for backlight. Fast responsive Bluetooth App to control and customize settings.

MIA's Description

Upgrade the control of your auxiliary lighting setup in your 2018–2026 Subaru Crosstrek with the Diode Dynamics D‑Switch Hub Mounting Kit (DD8784). This purpose-built mounting solution securely installs your D-Switch hub in the engine bay using OEM mounting points—no cutting, drilling, or permanent modifications required. The bracket is constructed from 10-gauge stainless steel and finished with durable powder coating to withstand harsh environments and long-term use. Its design positions the D‑Switch hub for optimal access without interfering with your fuse box or battery layout. Once mounted, the D‑Switch leverages Bluetooth-integrated control for up to eight customizable 12V outputs, including a dedicated backlight circuit for accent lighting. You can group outputs, set strobe patterns, or link functions—all controllable via app or the physical switch panel. Three trigger wires let you integrate the D‑Switch with your vehicle’s OEM signals (like high beams or reverse), while an ignition wire ensures automatic power cycling. This kit offers a clean, durable, and factory-conscious way to mount your switch hub, giving you intuitive control over lights or other 12V mods without cluttering your cockpit.
