• 2nd Gen 1994-2002 (major redesign): Big-rig styling that became the iconic Dodge Ram look and dramatically differentiated Ram from Ford and GM. Renamed Ram 2500 matching the numerical hierarchy. Engines: 3.9L Magnum V6, 5.2L / 5.9L Magnum V8, 8.0L Magnum V10, and the 5.9L Cummins 24-valve turbo diesel from 1998

• 4th Gen 2010-2018 (Ram becomes a separate brand): Chrysler split the truck line into an independent Ram brand for 2010, though still under Chrysler / FCA corporate ownership. 6.7L Cummins with progressively higher outputs, modernized interior, updated technology

• Cab configurations: Regular Cab, Extended Cab (historically Club Cab / Quad Cab, modern Crew Cab), and full Crew Cab
• Cummins turbo diesel heritage: The 5.9L Cummins from 1989 and later 6.7L Cummins from 2007 are the legendary features of Ram HD – the Cummins partnership dating to 1989 established Ram’s reputation for diesel capability and reliability, differentiating Ram from Ford Power Stroke and GM Duramax

Neutral Safety Switch Specifications

• Type: OEM neutral safety switch (park / neutral position switch)
• Function: Electrical safety switch that permits engine start only in Park (automatic) or with clutch depressed (manual). Prevents dangerous start with the vehicle in gear
• Construction: Electrical switch mounted on the transmission (automatic) or clutch pedal assembly (manual). Contact assembly closes the starter circuit only when the safe position is detected. Multi-pin connector for wiring integration
• Generation-specific variants: Early generations use mechanical rotary switches on the transmission valve body. Later generations use electronic switches integrated with the transmission range sensor. Specify generation and transmission type when ordering

Common Failure Modes and Replacement

• Failure modes: Switch fails to close in Park (engine will not start even in Park); switch fails to open in other gears (vehicle attempts to start in gear – dangerous); connector corrosion; internal contact wear
• Symptoms: No-crank in Park but cranks in Neutral; intermittent starting; vehicle attempts to start in Drive or Reverse; no-crank with a good battery
• Replacement: Access typically requires under-vehicle work at the transmission for automatic switches on the valve body. Disconnect the electrical connector, unbolt the switch, install the replacement, reconnect, and verify function through multiple gear position tests before returning the vehicle to service

Ram Brand Evolution Context

• Dodge Ram 1981-2009: Ram was part of Dodge’s pickup lineup. The 2nd generation big-rig styling made “Dodge Ram” one of the most recognized American pickup brands
• Ram Trucks separate brand 2010+: Chrysler split the truck line into an independent Ram brand as a strategic move to differentiate the truck identity from the Dodge car identity (which pivoted toward Challenger and Charger performance)
• Corporate context: Both Dodge and Ram remained under Chrysler / FCA / Stellantis corporate ownership throughout – the split was marketing, not corporate
• Naming timeline: Dodge Ram 250 (pre-1994) – Dodge Ram 2500 (1994-2009) – Ram 2500 (2010+ separate brand)
