Will this mirror work with my Dakota's existing wiring?

The mirror connects at factory mounting points, but electrical compatibility depends on your vehicle's harness and control module setup. Have your electrical system inspected before installation to confirm power and ground routing match this assembly.

Do I need to remove the old mirror to install this one?

Yes. You'll need to disconnect the old mirror's electrical connector and unbolt it from the door panel. The new mirror mounts at the same factory points, so no drilling or modification to the door is required.

Can I use this on either side of the truck?

No — this is a left-side mirror only. The housing and glass curve are shaped specifically for driver-side installation. Order the right-side assembly if you need both sides.
