How to Determine if Towing Mirror Turn Signals will Work on a 2010 Toyota Tundra CrewMax SR5 4x4 V8

Question:

The side mirrors I have on the truck are electric w/ heat, but no turn signal. I would like to add the tow side mirrors with turn signals.What do I need for them to work? Will they work and fit with the setup I currently have? What is needed for them to work properly?

We have two towing mirror options for your 2010 Toyota Tundra, I provided links to both for you. The turn signal feature in these mirrors will only work if the connection on your Tundra is factory wired with a turn signal circuit. You can test the connector on your mirror before ordering to be sure that the turn signal function is present.

To test the connection, use a circuit tester like part # PTW2993. Attach the alligator clip to a good ground, unplug the factory mirror and probe the metal tabs inside the connector with the turn signal activated on the vehicle. If you get the intermittent signal showing the turn signal is present, then the turn signal function in these mirrors will work for you. If that signal is not present the turn signal function will be inoperative.

Since your current vehicle does not have the turn signal feature, replacing the mirrors will, most likely, not give you the feature but it is worth a try to see if the signal is present. These mirrors use the plug and play system already integrated into your vehicle so the power adjust, and heat features will work.
