How to Install Turn Signal Mirrors

January 27, 2012

Turn signal mirrors are very important nowadays. Not only do they add style to your car's side mirrors,they also add safety to you and your vehicle while you are on the road. These turn signal mirrors generally are compatible to every kind of side mirror including JDM mirrors.

The safety feature of this turn signal mirror is that when you are in a car's blind spot, with the help of this turn signal, you will be warned that the car could be moving to your lane, compared to cars where the drivers must rely on the signal lights beside the tail lights.

Installing turn signal mirrors is easy and usually takes 1 to 2 hours. The tools that are needed to install these signals include a flat-head screwdriver, a Torx screwdriver, wrench, gauge wire, snake, electric tape, tap connectors and splicing connectors.

Step 1: Disassemble the Side Mirrors

To begin removing your side mirror, push it down and pull if from the top of your car to dislocate the ball and socket underneath the side mirror. After you have dislocated the mirror, it is now time to remove its cover.

Using a screwdriver, you should be able to push the clips, or you can just remove the cover by hand. You do not need to take extra caution when removing the mirror cover because you won't need the cover again since you are going to replace it with turn signal mirrors. 

After you have removed the mirror cover, the next thing is to remove the mirror off its hinge. This is done by removing three screws which hold the mirrors together with a Torx screwdriver. After you have removed the mirror from its hinge, you will see the hole where the wires for your turn signal mirrors should go through.

After this, you will see a rectangular piece of plastic trim near the mirror. You should remove this by applying force until it pops off. After you have removed the trim, you will be able to see three bolts. You need to do unbolt them. You should be able to visualize how to route the wires of your turn signal mirrors to the door of your car.

Step 2: Route the Wire of Your Turn Signal Mirrors to Your Car's Body

After you have dismantled your mirror, run your gauge wire from the mirror to the car's door, all the way to where you see all the wires lead to. After finding the rubber conduit, you can see a door trim beside all these wires. Tuck your wires in. Do the same procedure on the other side of the door, and you are ready for the next step.

Step 3: Route the Wires of Your Turn Signal Mirrors All the Way to the Headlights

The ideal way of doing this step is by snaking the wire from the mirror all the way to the engine bay. This is a very hard task. Improvising the wire's route would make it easier for you to tap it in to the signals.

To make your life easier, you will notice that in the previous step, you have your wires placed and routed through the rubber conduit. Now snake the wires from the front quarter panel all the way to the engine bay. Use a coat hanger to snake the wires through until you see it come out less than 12 inches from the headlight.

Step 4: Tap the Wires into the Turn Signal

You first need to identify the wires that you are going to tap into. These are the brightly wrapped wires that are bundled. You can tap with the use of a t-tap connector to the red and black wires.

Step 5: Attach Turn Signal Mirrors and Assemble Everything Back

To finalize things, attach your turn signal mirrors and assemble everything back. You should be able to tape the wires before you try to reassemble your mirror. You will find that installing turn signal mirrors is as easy as buying and installing aftermarket lights.
