What does the Brake Module add to my Signal® mirrors?
The Brake Module will add a "steady on" signal to both mirrors when the brake is activated. If a turn signal is activated, the module will send the turn signal to the appropriate mirror while maintaining the "steady on" signal in the opposite mirror.

Is it necessary to have the Brake Module installed by a professional? Can I do it myself?
Muth Mirror Systems strongly recommends professional installation of this kit. Ideally, installers who are experienced in installing aftermarket alarm systems, remote starters, or key-fobs should perform this installation. This is a universal or non-model specific kit and it is impossible for us to provide detailed installation instructions for all specific applications. Check out the instructions here.

Where can I have my Brake Module professionally installed?
You can call us at 1-800-844-6616 or download our Key Installer listing from here to help you find a recommended professional installer in your area. It is in .PDF format and includes key installers for each state as well as specific contacts and phone numbers within each company.

I already have Signal® mirrors installed. Can I have the Brake Module installed?
If your Signal Mirror® installation was done aftermarket, you will need to do the following: connect the red wire from each Signal® mirror directly to the Brake Module. The Brake Module will require that the turn signal connections that originally went to the Signal® mirrors will be connected to the Brake Module input harness. If you have OE Signal® mirrors and want to install the Brake Module, please contact us to see if that is possible.

Note: The Brake Module will not work with the 33-pixel design found on the 1997-8 Ford Expedition Eddie Bauer and 1998 Ford F150/250 Lariat.

I've installed the Brake Module and now the Signal® mirror flashes out of sync with the turn signals. Is this normal?
Yes, on some vehicles this will happen due to the vehicle's wiring system.

How detailed are the installation instructions? Where can I get a copy?
The Brake Module is a universal or non-model specific kit. This means that there are no detailed instructions for your specific model of vehicle. It is up to the installer to determine the best circuit location to tap into. Because of this, install times can vary greatly, and will depend on the installer's familiarity with the specific vehicle. The Brake Module installation instructions are found here.

What are some common installation errors?
To avoid causing the Brake Module to malfunction, please note the following:

• Make sure to connect the hot wire (usually red or brown) from the Signal Mirror® harness only to the outputs of the Brake Module. If you connect the hot wire to the vehicle and the Brake Module, the unit will malfunction.
• Verify that the turn signal wires carry only the turn function and not the brake signal too.
• If you are unable to locate the necessary wires, run a wire from the rear taillights to the Brake Module unit. The wires you will need are there (turn and brake).
