11-14 Chevrolet Silverado 2500 / GMC Sierra 2500 3500 Windshield Washer Pump

Will this pump connect directly to my truck's reservoir and wiring?

Yes. This pump is engineered to match your factory harness and reservoir outlet without adapters or modifications. Plug the connector and mount where the original sat.

What if my pump arrives and doesn't spray with the same pressure as before?

Return it within 30 days for a replacement. Each pump passes pressure testing before it ships, so a weak spray on arrival means you've got a defect, not an installation issue.

Do I need to drain the reservoir before swapping this in?

You don't have to, but it makes the job cleaner. If you leave washer fluid in, just be ready for minor spillage when you disconnect the old pump. Have a small towel or tray under the connection point.
