This is how I did the auto folding mirrors for my 2014 Platinum using eBay item number:255202906448.

100% of the install is in the drivers door using positaps and some butt connectors.
Everything but the trigger wire(s) will connect to wires coming from the smaller of the 2 connectors from the drivers door ecu.
There are 2 positive input wires, one for locking and one for unlocking. I only connected the locking input wire. This allows the mirrors to fold on lock and unfold with the ignition switch. The wire(s) to be tapped can be found on the factory connector on the inside of the drivers door panel just opposite of the exterior door handle pull.

I used Positaps for connections to wires from the smaller plug from the drivers door ecu for the following:
Batt 12v constant to Red Pin 3
Ign switched 12v to Yellow Pin 4
Ground to White/Black Pin 9

The only wire(s) Positaped not at the same connector:
Pos Lock Trigger to White (bigger gauge) wire from the power door lock
Pos unlock Trigger not connected

The following factory 4 factory wires coming from the smaller plug from the drivers door ecu, will need to be cut:
Cut Pink Pin 1 (MR - LH Mirror)
Cut Light Green Pin 5 (MR - RH Mirror)
Connect together the Pink and Light Green wires leading back to the ECU
Connect together the Pink and Light Green wires leading to the mirrors
Cut Black Pin 2 (MF - LH Mirror)
Cut Brown Pin 6 (MF - RH Mirror)
Connect together the Black and Brown wires leading back to the ECU
Connect together the Black and Brown wires leading to the mirrors

The remaining 4 wires from the aftermarket harness attach to the other side of the 4 butt connectors connecting to the cut factory wires at the same smaller plug coming from the drivers door ecu:
Pink (cut from the Y harness thats setup to plug into the 07-13 tundra mirror switch) to Pink and Light Green (MR) wires leading back to the ECU
Orange (cut from the Y harness thats setup to plug into the 07-13 tundra mirror switch) to Black and Brown (MF) wires leading back to the ECU
Green (cut from the Y harness thats setup to plug into the 07-13 tundra mirror connector) to Pink and Light Green (MR) wires leading to the mirrors
Blue (cut from the Y harness thats setup to plug into the 07-13 tundra mirror connector) to Black and Brown (MF) wires leading to the mirrors

If you decide to do it, you'll see why I wonder why there isn't a vendor who makes an easy diy setup using a Y harness.

Great write up. I’ll most likely attempt this assuming the connectors are available over at corsa technic. Thanks again

It's a 10 pin connector, nothing special. Pins 1-4 on the top row and 6-10 in the second. Everything can be in Y harness except for the 2 trigger wires which can be in a second Y harness. If the desire is to have the ignition switch unfold the mirrors then just cut 1 wire. Create that harness and offer it to all the Platinum and 1794 guys.

From a risk management standpoint, I probably should do my due diligence and say (insert disclaimer here).

Also this still doesn't address what a lot of people were looking for in this thread, which was to illuminate the switch itself. I posted here because I was able to use a lot of the information from here to get auto folding on my Platinum, to which I am thankful for.

Many thanks but I will not have time to get into this before surgery unfortunately

Fortunately the internet will still be here when you are ready. I hope all goes well for you and recovery is quick.

So I was checking Google to find out why my power mirror switch didn't light up and it brought me here where I learned it doesn't light up because it's not supposed to. This is my second Toyota truck and I love the build quality of them but good Lord they cut corners in some strange places. LOL!
