Technical Stereo wire block

[Wopen]

I’m looking to install an aftermarket android stereo and I’ve struggled to find out what the blue, green and yellow block of wires is for. It only has 3 wires in the green part and I have been unable to establish what it’s for.

Steering wheel buttons, if fitted

No buttons fitted, so I can ignore that block. Makes sense

Just goes to the steering clock spring connector

So yep just ignore

Just been messing with this recently. Youll find Key1 and Key2 these goto the green connector top and bottom "SWC" wires. Middle one is earth. If you have no buttons you can use non latching push buttons and make your own switches on a resistor ladder. ie buttton1 200ohms then button2 300ohms and button3 400 ohms. When you program the android head unit it will learn the the relevant resistances to what ever button you program it to! If you fit a wheel with a clock spring these are your key1 and key2 wires. ie if you where to fit a 100hp or abarth 500 wheel. If you dont understand what ive just said!? Ignore it
