Will this fit my existing mirror housing without any modification?

Yes. This lens is cut to factory spec and mounts directly into the OE mirror frame. No cutting, drilling, or adapters needed.

Do I need to solder or wire this into my electrical system?

The heating element harness connects to your factory mirror wiring. Confirm your mirror housing has the heating connector before ordering—some base-model trims may not have the provision.

Can I return this if it doesn't fit?

Test-fit before fully installing. Once the heating element is wired in, most retailers treat it as a final sale. Confirm fitment on your specific mirror assembly first.
