Diesel Glow Plug Relay for Ram ProMaster

Standard Ignition RY1848 is a 12-volt diesel glow plug relay built for reliable cold-start control in Ram ProMaster 1500, ProMaster 2500, and ProMaster 3500 applications. It uses a female square connector, male terminals, and an included mounting bracket for a direct-fit service replacement.

Key Features

  • 12-volt diesel glow plug relay for glow plug circuit control
  • Female square connector with 8 male terminals
  • Mounting bracket included for secure installation
  • Composite housing helps protect against heat and under-hood exposure
  • Aluminum contacts support durability and long service life

Detailed Description

Standard Ignition RY1848 is an emission control relay used to manage glow plug operation on diesel-equipped Ram ProMaster vans. It is engineered with a composite housing and aluminum contacts to handle demanding under-hood conditions while maintaining consistent electrical performance. This part cross-references Monroe Shocks & Struts (e.g., 68167867AA, GPR302) for the same application. If you are replacing a diesel glow plug relay on a Ram ProMaster 1500, ProMaster 2500, or ProMaster 3500, RY1848 provides the connector style, terminal layout, and mounting configuration needed for service work.

What It Helps Fix

  • Hard starting during cold weather
  • Glow plugs not receiving proper relay control
  • Intermittent diesel preheat operation
  • Relay failure caused by heat, moisture, or contamination
  • Electrical connection issues at the glow plug relay circuit

Installation Notes and Tips

Verify connector shape, terminal count, and mounting location before installation. Confirm the vehicle uses a 12-volt glow plug relay and compare the existing part number to RY1848 when servicing Ram ProMaster 1500, ProMaster 2500, or ProMaster 3500 models. Inspect the harness terminals and surrounding wiring for corrosion, heat damage, or looseness before installing the replacement relay.

Quality Assurance

Standard Ignition manufactures this relay in a TS16949 and ISO9001 certified facility. The housing, contacts, and epoxy sealing are selected to support durability in harsh under-hood environments.
