Will this mirror work with my truck's existing wiring harness?

The mirror uses factory electrical connector points on your Tundra. Confirm your truck's harness has power, ground, and signal wires at the mirror location before installation — most second-gen Tundras do, but test before committing.

How do I activate the heater and heated glass?

Heating function and power adjustment operate through your truck's existing dashboard controls or stalk switches. Consult your vehicle's owner manual for the exact control location and operation sequence.

Can this mirror be installed without drilling or permanent modification?

These mirrors mount at factory rocker and bracket points — no drilling required. Installation method details and torque specs should be verified against your service manual to ensure proper panel fitment and electrical integration.
