Product description
Our 12V Glow Plug Preheater boards (commonly known as Glow Plug Timers) have higher corrosion-resistance than OEM boards, meaning they’re perfect for reviving your rig. Plus, they're plug-and-play, meaning they're ready to go when you get them.
 
Features
SuperGlow
This board serves as a direct replacement for the 2H preheat timer while emulating the SuperGlow functionality of the OEM Toyota board. By leveraging digital technology, it accomplishes more with fewer components, enhancing reliability and reducing the likelihood of corrosion over time.
 
Manual timer
The manual timer is an optional feature that effectively transforms the board into a 5-second glow plug timer.
 
Automatic fault detection
The automatic fault detection feature can identify any broken sensors or short-circuited wires and promptly notify you of the specific fault through the glow plug indicator.
 
Wilson Switch
The board has an input for a Wilson Switch, which allows you to overwrite the system at any time by turning on the main glow plug relay.
