Will this plug directly into my door harness, or do I need an adapter?

This switch uses factory connectors that match the OEM harness. No adapter or custom wiring needed — plug it in and test before reinstalling the door panel.

Do I need to pull the whole door panel apart to install this?

Yes. You'll need to remove the interior door panel to access the switch pocket. Once out, disconnect the old switch from the harness and swap it in — the mounting points are factory-original.

What if the switch doesn't work after I install it?

Test it before you reassemble the panel. If the window won't move, verify the connector is fully seated and check your door's fuse. If the switch is faulty, contact ModSupply for a replacement or return within the standard window.
