Remote control - wirings

[patso_pro]

I've purchased a Clarion DB288RUSB head unit and now the question comes to the wheel remote controlling. The car is Opel/Vauxhall Vectra B 'built '99. I rather prefer making wirings on my own to purchasing an adapter but some help is needed.
There is a remote control stereo jack on the HU's back. And here is how my ex car audio's connectors looked like:

Thanks in advance

buy an adaptor! i'm pretty sure the vauxhall and clarion protocols are completely different and you can't just join them together hence why you need the adaptor
