Does this come with the mirror backing plate or just the glass?

This is the glass lens only. The heated element is integrated into the glass itself — you'll keep your existing mirror backing and backing plate when you swap this in.

Will this plug directly into my vehicle's wiring?

Yes. This lens is designed for direct electrical integration with factory mirror harnesses on these Nitro and Liberty models. No adapter or modification needed.

Can I install this myself, or do I need a dealer?

Mirror glass replacement is straightforward DIY work — most guys handle it in under 20 minutes with basic hand tools. Your service manual will walk you through the mirror housing removal. Once the old glass comes out, the new lens seats the same way.
