Will this pump work with the factory hose and connector?

Yes. This pump uses OEM-compatible connections, so your existing washer lines and reservoir hookup stay in place — just swap the pump out.

Does this pump come with a relay or wiring harness?

Pump assembly only. Use your existing factory wiring and relay — no additional electrical components needed.

What if the pump doesn't spray right after installation?

Check the washer fluid level first, then verify hose connections are tight and free of kinks. If pressure is still low, air may be trapped in the lines — run the pump for 10–15 seconds to purge.
