Hi Roge, This harness is not installed internal to the mirror, it is installed external so it sounds like you may be looking at the wrong video. Please reach out to support@boostautoparts.com for assistance. Thanks, -The Boost Auto Team

Works great

Installs and works exactly as advertised. Be sure to tape the module below the plug so the door panel will fit back on without hitting it.

Dual function mirror lights

Easy to install, works as intended. Use caution when taping up harness as it needs to be flat to get the door panel back on.
