Application Details

Compatible With 2006-2008 Honda Pilot and 2003-2006 Acura MDX applications listed in the fitment data. Standard Ignition NS-328 is a direct-fit neutral safety switch for vehicles that use this connector and mounting style, helping maintain proper park and neutral start logic. This part cross-references Honda 28900RDK003 and 28900RDK013 for the same application.

What It Helps Resolve

• Engine starts only in certain gear positions
• No-crank condition when the shifter is in Park or Neutral
• Intermittent starting circuit signal at the transmission range switch
• Incorrect park/neutral input to the starting system
• Transmission range switch electrical faults on listed Honda and Acura models

Installation Notes

Verify connector shape, terminal count, and bolt-mount location before installation. The switch uses a female rectangular connector with blade terminals and no wiring pigtail, so the vehicle harness must match the OE-style connection. Confirm shifter adjustment and transmission linkage position during replacement to ensure proper park/neutral operation.

Quality Assurance

Standard Ignition supplies electrical components for service replacement applications, and NS-328 is built to match the listed fitment and connection requirements for the specified Honda Pilot and Acura MDX vehicles.
