Hey thank you for your help,
so the: (pink) went the red wire (A yellow) went to the yellow wire You made a ground for the black wire? What about the orange and blue wire? I've noticed you have lift the speaker wire in the original socket? The problem I'm having is while I'm driving the radio cuts off back on and so on haha I have to hit the side unit for it to come back on I think there's a loose wire somewhere |

Those are the connections yes. I would check your own connections with the wiring diagram of your particular radio. I did extend the black ground wire on my radio and crimp on a spade connector for grounding.
For the speaker connections I cut the wires and crimped on 4mm insulated bullet connectors for connecting to the corresponding ISO wires on my aftermarket radio. The orange wire on an ISO 10487 connector is for headunit screen dimming, which is a feature that my headunit did not support, so it remains unconnected. The blue wire on the other hand is used for various things, amongst which is connecting it to an external amplifier for remote power (like the ignition for your headunit, wakes it up to draw power only when other accessories have power). If you are not considering adding a subwoofer or other audio gear requiring an external amplifier, leave this unconnected also. So to clarify, with an additional aftermarket headunit mounted, the only connections to the original headunit (connector M51 W) are Yellow-Red, the two Yellow wires and a Red wire (pins 1-4). None of the speakers are connected to the original headunit (pins 5-12). Useful links: Pinout for the Primera headunit The ISO standard for aftermarket headunits |

Yes, that is the sole reason i've "tapped into" the power wires of the original unit instead of cutting and connecting them directly to the replacement one. This way there is no possibility to trigger the SECURE message (at least to my knowledge, if the original radio doesn't self-destruct).
