Step-by-Step Chevy Tow Mirror Installation

Step 1: Disconnect Battery Power

Before working on electrical components: Disconnect that negative battery.

Step 2: Remove the Interior Door Trim Panels

Pried the little clip out here, take the door lock contraption off.

Using a small pick or flathead screwdriver, remove the small plastic cover plate behind the interior door handle to reveal the door lock/latch screws.

Remove the black plastic inner triangle cover on the upper inside corner of the door, directly opposite the mirror and pry up the door panel.

Step 3: Unbolt and Remove the Stock Mirror

Remove the three mounting nuts holding the mirror assembly. 

Safety Step:

Hold the outside mirror housing with one hand through the open window while loosening the nuts with your 10mm socket. This prevents the mirror from falling and damaging your outer door paint.

Step 4: Install the New Towing Mirror

Inspect the rubber weather seal on your new towing mirror. Ensure it sits flush against the base to prevent wind noise and water leaks.

Using your ratchet, tighten the 10mm nuts evenly in a diagonal pattern.

Step 5: Wiring Harness Installation

Plug the extension harness into the connector.

Use a coat hanger or wire puller to guide the extension harness through the rubber door boot and down into the driver-side cabin under the dashboard.

After that, repeat the exact same process on the passenger side.

Slide heat shrink tubing over the Blue(DRL) and White wires(Backup Light), join the passenger side and driver side wires together, then use a heat gun to seal and insulate the connections.

Step 6: How to Connect to the fuse box

Route the wires for the Blue(DRL) and White wires(Backup Light) through the firewall grommet on the driver’s side into the Under-Hood Fuse Box. 

Using an add-a-circuit fuse tap, connect the DRL wire to Fuse #33.

And the Reverse Light wire to Fuse #10 in the fuse box to power both auxiliary functions safely.

Step 7: Test Functions and Resemble All the Door Panel Parts

Before snapping the interior door panels back into place, perform a systematic test of all electrical features:
