How do I identify the right part before buying?

Compare the part numbers stamped on your original relay to the cross-reference list and inspect the connector: you should see three plugs and four pins. If the plug count or part number doesn’t match, this relay may not mate correctly and you should verify with a parts diagram or dealer.

• Check for OEM numbers: 37710-115-0000, 37700-055-0000, 37705-115000-0000, 376800010, P115000377050000
• Confirm the 3-plug, 4-pin connector layout visually before purchase
• Compare shape and mounting points to your original relay for fitment

What should I expect during installation and maintenance?

Installation is typically a simple electrical swap: disconnect the battery, remove the old relay, and plug the new unit into the harness. No special tools are required beyond common hand tools, but basic electrical caution and a secure mounting are important for reliable operation.

• Disconnect battery before replacement to avoid shorts
• Hand-tighten mounting fasteners and verify solid connector seating
• Periodically inspect terminals for corrosion and tightness
