How to Install Towing Mirrors in Four Steps
If you are bringing a trailer along on your next trip, then installing a pair of towing mirrors will help your drive become a lot easier and safer. Unlike your regular side mirrors, these components extend out further from your vehicle, giving you a better view of what is behind you and your trailer. This is a huge help when you are in the middle of traffic or when you are backing up. To learn how to install these towing mirrors, follow the guide below.
Required skill level: Expert
Needed tools and materials
Removing the trim piece and stuffer gasket
To start, open the door-either the driver's or the passenger side, whichever you will be working on first-and roll the window down completely. Gently pull the top edge of the corner door trim piece away from the door. Once it is disengaged, pull the trim piece upward to remove it from the door trim panel. Then, gently take the gasket from the door pocket. Set these pieces aside for reinstallation later.
Detaching the electrical connector
If your side mirrors are manual or if you are installing manual towing mirrors, then move ahead to the next step. However, if they are electrically powered or you are installing electric towing mirrors, do this procedure first: pull the wiring harness out of the door to access the plug. Then, gently pry the locking tab on the side of the plug and pull the harness away. Do not let the harness and connector fall into the door cavity.
Removing the side mirrors
While your assistant holds the side mirror, use a 10 mm open-ended wrench to remove the three 10 mm nuts inside the door. Make sure not to drop them into the door cavity. Then, slowly remove the mirror from the door. If your car is equipped with an electrical harness, feed it through as the component is removed.
Installing the towing mirrors
Take out the mounting plates for the towing mirrors. These will mount on the doors of your vehicle, where you will attach the component. Place each mounting plate in position on each front door and, using a chalk, mark the areas where the screw holes will need to be drilled. Once these are marked, get your drill out and select a smaller sized drill bit than the metal screws that you will use to attach the plate. Drill the holes for the mounting plates and then screw them into the body of the vehicle. Mount the rest of the towing mirror assemblies to the plate. Finally, while sitting inside your vehicle, adjust the mirrors until you have a clear view behind your truck.
