I finally installed power fold tow mirrors on my 2014 Tundra CrewMax Limited.
I want to thank the following members for their contributions on this mod. I did several searches for this, and these members completed various mods that made this mod possible. So Thank You to "roboots21". He had the link for the switch on ebay, the rectangular connectors, and information on the wiring for the power fold option. Thank You to "safety77". He figured out the pin locations for the BSM leds. I took the information, and ran with it to install my power fold Tow Mirrors.
First my truck has the BSM system, and that had to be dealt with before moving on to the tow mirrors. Otherwise the truck sends an error message due to an open circuit in the mirror harness. So I located the BSM wires in the mirror harness. They are as follows:
Driver mirror:
Top row pin #9 purple wire is "+" BSM.
Bottom row pin #5 white w/ black stripe wire is "-" BSM.
Passenger mirror:
Top row pin #9 tan wire is "+" BSM.
Bottom row pin #5 white w/ black stripe wire is "-" BSM.
I bought amber LED lights off of amazon. These worked great, and easy to graft into the harness.
Amber LEDs.
I installed one in each interior door cap. The housing is a little long so some clearance needed to be done with a 7/8" hole saw. I cut, and spliced LEDs into the harness. I used insulated spade connectors so removing, and replacing will be easier in the future.
Now onto the power fold mirror switch, and wiring. I bought a new mirror switch off Ebay for $35.
Mirror switch.
Mirror switch wiring is as follows:
Pin #8
Pin #9
Wiring at the mirror connector is as follows:
Bottom row pin #7 "+" mirror fold
Bottom row pin #8 "-" mirror fold
I bought the following to add the circuits into the factory connectors:
Mirror rectangular connector
Ratcheting crimp pliers
I ran 22 gauge wire from the mirror switch to each mirror, and inserted them into the proper pin locations. I should of used 24 gauge wire, but 22 was all I had. The 22 worked, but a little effort was needed to fit into the connectors at the mirror.
You will need a larger rectangular connector for the mirror switch circuit. They are slightly larger than the pins at the mirror. I was able to spread them with a metal pic.
I believe this is the correct size.
Switch rectangular connector
I hope this helps anyone wanting to install power fold tow mirrors.
