Right, I launched the 150 into the 20th century with auto-folding mirrors
I bought a Auto-folding mirror kit from AliExpress for around £18 including postage.

They asked for a photo of the back of the mirror cluster so they could send the correct loom.
I sent this and it was sufficient.
The module arrived within a week which was pretty impressive.
Cluster out, loom adaptor in between and you can put it all back (Forgot pic

)
Remove the kick-panel in the driver's foot well.
Next to tap off 12V (non-switched) which was easy enough - came off the door-control plug.
The next bit was a bit of a faf and took me a while to find as there are many wires and no instructions.
You need the lock pulse and the unlock pulse for when the doors lock and unlock. I thought I had found it on the white plug and after convincing myself it was correct and the module was broken I realised they were for the indicator flashes.
There are 4 plugs - going down, a black one, white one, grey one and yellow one.
The 12V can be tapped off the thick red wire on the white plug.
The lock and unlock signals are on the upper black plug. While plugged in, the bottom row of wires, the green and blue ones. (Blue one pictured above)
The green wire from the module goes to the blue one and the grey module wire goes to the green wire.
Tap those off, hold close the door switch and arm the alarm.
Like a 21st century car the mirrors whirr into action
I would love to understand why Toyota does not do this as a factory option. It would be even easier to do it in-house as it's all CAN-bus anyway. Ho hum.
