Will this work with my factory connectors and wiring?

Yes. This assembly uses OE mounting points and electrical connectors — your existing wiring harness plugs directly in without adaptation.

Do I need to replace both headlights at the same time?

Not required, but recommended. If one is failing or damaged, the other is likely aging too. Replacing as a pair keeps brightness consistent.

What if the lens is cloudy or the reflector is damaged?

This is a complete assembly — lens, reflector, and housing all come together. If damage is visible, replacement is your best option for proper beam performance and safety.
