Wells Diesel Glow Plug Controller

The Wells Diesel Glow Plug Controller (also called a glow plug control module or glow plug relay controller) manages the electrical current sent to a diesel engine's glow plugs during cold starts. Wells Vehicle Electronics designs and manufactures it as an OE-grade replacement.

Key Features:

• Controls the timing and duration of current flow to the glow plugs for the pre-heat cycle
• Designed to meet or exceed OE specifications in form, fit and function
• Direct-fit replacement design for straightforward installation
• Made by Wells Vehicle Electronics, a supplier of vehicle electronics for OE and aftermarket applications

A failing glow plug controller can cause no-start, hard-start or extended-crank conditions, especially in cold weather. Replacing it restores reliable glow plug operation and cold-start performance.
