2003 holden Berlina v6
I have a 2003 vy holden Berlina v6 and the oringal owners of the car have cut the headunit wires before the harness and I have no idea what wires mean which! I only know earth, the green and white wire seems to give me a check engine light whenever touching certain wires. If someone can tell me which wires mean which that would be most appreciated!

The current harness has been cut and I just have a bunch of wires all the colors seem to be there but can I hook this up to my aftermarket jvc without having to setup another plug and play setup?

After doing this do I just put say 2 wires into one then twist them?
