Will this mirror plug straight into my existing wiring harness?

Yes—this is an OEM assembly designed for factory connection points. Your vehicle's mirror wiring harness should connect directly without modification. If you've replaced your mirror before, the plug will seat at the same location.

What if the heater or power function doesn't work after install?

Check your vehicle's fuse panel for the mirror/heated seat circuit first—it's usually shared. Verify the wiring harness is fully seated. If power reaches the mirror and neither function responds, the assembly may need testing or replacement; contact support with your order number.

Can I use just the heated feature without powering the adjustment motor?

Both functions are part of the same assembly and operate on the same electrical circuit. You can control each independently through your vehicle's interior switches, but you cannot disable the motor entirely without cutting power to the whole mirror.
