Installation Notes and Tips

Verify the relay style, terminal count, connector shape, and amperage rating before installation. This part uses a female rectangular connector with 4 male blade terminals and does not include a mounting bracket. Confirm OE reference numbers and vehicle-specific notes such as Niles, Miyamoto, 4 Term., or OE No. 25230-9B900 where listed in the fitment data. For best results, inspect the relay socket for heat damage, corrosion, or loose terminal tension before installing the replacement.
