    Hello everyone
    When I get my VNL it has factory sound system with sub and amplifier,
    While accessories and ignition modes my radio player and clear amplifier was heating too much. After for a while, the radio units electronic card is gone. Previous owner installed so many cables and stuffs but he removed all devices and left a cable debris.
    I get a Sony head unit and trying to install it. I search on internet and here but can’t find double 8 pins diagram.
    I found this diagram at Volvo USA but can’t see double eight pins information
    Here is diagram for sub and amplifier network

    Also I’m not sure about connectors;

    Red is constant power... yellow is switched power... blue is remote (turns the AMP on and off)

    Stereos are all wired the same... just Google Stereo wiring installation guide... it's really pretty easy.

    From left to right
    1- Iso connector (double 8)
    2- yellow with one cable- What is this?
    3- blue with two cable, what is this?
    4- Black Power cable, For what?
    5- antenna, For Sirius, I think
    6- another antenna for what?
    Could you please answer that questions? Is anybody know what they for?
    Also, I need double eights diagram, The connector selling on the market cable is not matching because Volvo do not use the standard wiring. For example In US , black cable is For ground, but ####ing Volvo use green for ground what the ####! I watch many videos when people get a connector harness kit for double eight pins are not matching.

    Thank you sir, but it’s not that easy because Volvo has a different wiring standard
