Auto fold mirrors with unlock/lock universal module T25

[04T25]

Hi there,

I'm new to this forum so its nice to meet everyone.

After years of owning my avensis, I thought its time to make my life more easier and buy one of those auto folding mirror modules from eBay(link of module below).  I want to try and install it myself as it seems pretty straight forward however I don't know which wire to tap into. The part number of the module that is in the avensis is called 183575. 

I was hoping if someone in this forum has maybe previously done this install or maybe knows what wires do what in the mirror switch module.

Hope to read everyone's replies soon!
