Q: What are the benefits of the MultiFunction Module?
A: This module is specifically designed to provide additional visibility to your Signal® mirrors in situations beyond your turn signal. It will provide you with up to 4 additional features that will use your existing Signal Mirror® display. You can choose to use any combination of one to all four features. Go here to see more about the MFM.
Q: What if I just want the brake feature?
A: Save some $ and just get our Brake Module.
Q: Is the MFM “rugged” enough to handle vibration? Where can it be mounted?
A: Yes, the MFM has been tested against OEM vibration testing standards. The MFM can be mounted in any interior location. The MFM has not designed to be exposed directly to moisture or weathering conditions.
Q: Is it necessary to have the MFM installed by a professional? Can I do it myself?
A: 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. The complexity of this install is about the same level as a full-featured aftermarket alarm system. Check out the instructions here.
Q: Where can I have my Multifuction Module professionally installed?
A: 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.
Q: I already have Signal® mirrors already installed. Can I have the MFM installed?
A: If your Signal Mirror® installation was done aftermarket, you will need to do the following: The two-wire cable from each Signal® mirror must be connected directly to the MFM. There must not be any other connection between the Signal® mirror and the MFM, including any connection to ground. The MFM will require that the turn signal connections that originally went to the Signal® mirrors will be connected to the MFM input harness. In addition to the turn signal connections, connections will be made to the brake, reverse, door and 12 volt switched ACC circuits to take advantage of the additional features that the MFM can provide. If you have OE Signal® mirrors and want to install the MFM, please contact us to see if that is possible. Note: The MFM will not work with the 33-pixel design found on the 1997-8 Ford Expedition Eddie Bauer and 1998 Ford F150/250 Lariat.
Q: Will the alarm tick run my battery dead?
A: The draw of the MFM with the alarm tick feature is very low. The draw over time will amount to about 1 amp hour every 6-7 days. The means that unless you are going to store your vehicle for an extended period of time, you will not need to disable this feature.
Q: What are the dimensions and weight of the MFM?
A: Without the wire harness, the MFM is 3.25 x 4.38 x 1.5 inches and weighs 4.6 ounces.
Q: How many wire connections are needed to activate all the features of the MFM?
A: If every feature of the MFM is enabled, typically 9 wire connections are needed, including power and ground. In addition, two wires must be connected to each Signal® mirror.
Q: What lengths of wires come with the MFM?
A: The input harness cables are six feet in length.
Q: How detailed are the installation instructions? Where can I get a copy?
A: The MFM is a universal or non-model specific kit. This means that there are no detailed instructions for your specific model of vehicle. We do provided detailed instructions on what circuit each input wire has to be connected to, but 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 MFM installation instructions are found here.
Q: What are some common installation errors?
A: To avoid causing the MFM to malfunction, please note the following:
- You must connect the Signal® mirrors to the MFM only. If the Signal Mirror® harness is connected to the vehicle too, it will cause the MFM to malfunction.
- Verify that the turn signal wires carry only the turn function and not the brake signal too.
- To activate the MFM for each feature, you will need to tie into circuits that go from 0 volts to 12 volts when activated (active high), or from 12 volts to 0 volts when activated (active low).
- If you are unable to locate the necessary wires to activate the features you want to use, run a wire from the rear taillights to the MFM unit. Most of the wires you will need are there (turn, brake, and reverse).
Q: What if I need help while completing my MFM installation?
A: Call our tech support at 1-800-844-6616 and a Muth representative can help you with your specific situation.
