Steering Wheel Control Wiring to android unit

[davemustang]

Hi everyone, i bought a steering wheel control unit from Aliexpress as found below, for Nissan March K13 2013

https://www.aliexpress.com/item/4000092178257.html?spm=a2g0o.order_list.order_list_main.5.6f821802Yfawv7

There is no manual and hence i am unable to know which wire is power, ground, key 1 and key 2, sources on the internet are confusing.

If anyone has ever installed a steering wheel control for nissan march k13, please i need your help and experience for finding the right color for each function.


Thanks.
