Will this mirror work with my truck's existing power window and door lock controls?

This mirror is wired for power adjustment via factory electrical harness. Confirm your vehicle has the factory power mirror circuit before installation — some base models came with manual mirrors only.

Do I need to disconnect the battery before swapping mirrors?

Yes. Disconnect the negative battery terminal before unplugging the old mirror and wiring the new one to avoid short circuits or airbag issues.

What fasteners do I need to mount this?

Fastening hardware is not included with this assembly. You'll need the original bolts from your truck or equivalent hardware — most Colorado mirrors use three bolts at the door panel. Have your hardware on hand before removal.
