FAQ
What is the difference between 5677803 and 4076930?
Both refer to the same Cummins oil pressure switch. 5677803 is the current Cummins part number; 4076930 and 4076931 are superseded numbers for the same switch.
Does this fit all 2002 Dodge Ram Cummins?
Important: Some 2002 models use a 3-wire connector. This switch (5677803) uses a single-wire connector. Inspect your connector before ordering — the single-wire version will not work on 3-wire connector applications.
Are there vocational equipment applications?
Yes — Cummins ISB-powered construction and vocational equipment with the same engine platform use this oil pressure switch.
Do you ship to my location?
Yes. AIM Rentals ships Canada-wide from Kelowna, BC.
