How
can I make my installation as smooth as possible?
Here
are some tips to consider prior to performing your installation:
- Verify
that you have the correct kit for your vehicle.
- Work
in an area that will allow you to open your doors wide without damaging
them on walls, benches, another vehicle, etc.
- Wear
safety glasses and gloves.
- Make
sure you have use of either a voltmeter or a test light so you can verify
that you have the correct wires prior to making the connections.
- Read
the instructions! Our instructions will recommend basic tools, which
you will need during your installation. They will also demonstrate the
proper way to remove your mirror glass so as not to damage the housing
or motor. In addition, they will generally provide you with a step-by-step
layout of the entire installation.
- If
you are installing the Wide Angle Signal®
Mirror, Brake Module, or MultiFunction Module, keep in mind that the
instructions for these kits do not contain specific wiring directions
and you will have to determine the correct wires yourself. You may be
able to get wiring information from your dealership or a business that
specializes in 12 volt accessories. You can also "pull" your
taillights and see what color wires are there to see if those same wires
are available under the dash area. If you're not sure, it may be time
to get professional installation.
- If
you are unclear about something with the instructions, please contact
us.
I am installing
my Signal® mirrors and there are two
extra wires that are not for the heated feature. What are they for?
Your
vehicle is probably equipped with electrochromic (EC) mirrors. When installing
Signal® mirrors on a vehicle equipped
with EC, there are two extra wires connected to the internal OE mirror.
These should be identified as the EC feature and should be tied off correctly
so as not to short anything or interfere with the travel of the mirror.
I have heated mirrors,
but really don't care about that feature. Can I use the unheated ones
for my vehicle?
Yes,
you can. It will be important to cap off the heater wiring in each mirror
so you don't short out the circuit. Also, make sure to locate the wires
in an area that will not interfere with the travel of the mirror.
I've installed
the Signal® mirrors and now one (or
both) mirror(s) also go on solid when I apply the brakes. What is going
on?
Your
vehicle has wiring that contains not only the turn signal, but the same
wire also contains the brake signal. If you want to have the brake signal
too, probe to locate the wire with the brake and turn in it. If you don't
want the brake feature, probe to find the correct one that carries only
the turn signal. Not all vehicles are wired this way. If yours isn't and
you want the brake signal too, check out our brake
module.
The wire called
out in the instructions isn't where it's supposed to be. Now what?
We
do our best to call out proper wire colors and location(s) for the turn
signal circuit. If you can't find the wires, you will have to use your
test light or voltmeter to locate the correct wires. We recommend you
look at the color of the wires at the taillights first and see if those
wire colors carry up to the dash area.
My factory mirrors
have a black plastic backing, which gives them a thicker look. The Signal®
mirrors do not have this backing. Is this okay?
The
Signal® mirror was designed to be a
"floating mirror" and will not affect your view in any way.
The size of the Signal Mirror® glass
has been adjusted to compensate for the lack of the backing.
The Signal
Mirror® mounting does not look like the
original mounting. What is going on?
Verify
that you do have the correct kit for your vehicle. If you do, then compare
the pictures in the instructions to what you are seeing in the housing.
Many times, it's possible to actually remove part of the motor mount when
you are removing the original mirror. If you have done this, remove the
piece from the back of the mirror and reinstall it carefully onto the
motor.
I installed my
Signal® mirrors, but now my fuses keep
going out. What would most likely cause this?
This
is most likely due to a short in the newly installed wiring. You will
need to trace the Signal Mirror® harness
to see if there are any breaks in the casing of the wiring that may allow
the wire to short out the circuit and blow the fuse. When you find the
damaged area, shrink wrap it or wrap it in electrical tape to prevent
the short.

I had my Signal®
mirrors installed and suddenly my mirror does not light up when the turn
signal is on. What happened?
Here
are things to check:
- Check
the fuse for the turn signal circuit.
- Check
the wiring for that mirror and verify that both connections have not
come loose.
- Check
behind the mirror itself to see if the mirror has been disconnected
from the harness. If it has, plug it back in.
- If
you had the mirrors professionally installed, go back to the installer
for help.
Troubleshooting tips:
- At any time, you can first check the function of a Signal® Mirror with a 9-volt battery. If the mirror lights up, the problem is located with the wiring in the vehicle.
- Signal® Mirror(s) won’t activate with the vehicle’s turn signal:
- Check to see if the Signal® Mirror is plugged into the wire harness behind the mirror glass
- Test the connection behind the Signal® Mirror by probing for power
- Verify the Signal Mirror® wire harness was not damaged or cut during installation
- Check the connections to both the vehicle’s turn indicator wiring and the ground
- Probe the vehicle’s wire that was tapped and verify it’s the correct wire
- Signal® Mirror(s) worked for a period of time after installation and stopped working:
- Check to see if the Signal® Mirror is plugged into the wire harness behind the mirror glass
- Test the connection behind the Signal® Mirror by probing for power
- Verify the Signal Mirror® wire harness was not damaged or cut
- Check the connections to both the vehicle’s turn signal wiring and the ground
- The fuse “blows” when the turn indicator is activated (check the side that causes the fuse to blow):
- Check the Signal Mirror® harness for a bare wire that may be contacting the body of the vehicle
- Check the wire tap to be sure the metal jumper is still covered and not contacting the body
- Check the Signal Mirror® harness to see if it has been pinched and the wire insulation may be damaged allowing the wire to contact the body
- Wire colors and/or location of wires the instructions say to tap are not correct:
- Check for a bundle of wires that may be wrapped up hiding the wire colors
- Pull the tail-lights and probe there to determine what the wire colors are; try to find that color in the same location that’s been called out in the instructions
- Check in the door sill on either side of the vehicle for the correct wire color(s) from the instructions and probe to verify they are the correct wire(s)
