1998-2003 Toyota Sienna Windshield Washer Pump with Dual Pumps

Do I need any adapters or connectors to wire this in?

The pump assembly uses factory electrical connectors — your existing wiring harness connects directly. No adapters needed if you're replacing the original unit.

Will this fit if I have an aftermarket washer fluid reservoir?

This pump mounts at the factory tank locations. If your reservoir is stock-style, installation is straightforward. Confirm your tank's pump port matches before ordering.

What if one circuit stops working after install?

Each pump circuit operates independently — if front or rear spray fails, check washer fluid level and hose blockages first. A kinked or frozen line is the most common culprit, not the pump itself.
