Right. Hello everyone I have a 86 golf, so pre 90's spec. It came with a headunit but trying to figure out how to fix it, I have discovered I have only 1 tweeter and 1 speaker on the rear parcel shelf. No wires connecting them to the stereo and no sign of the original loom. So I pull the headunit out to see whats occuring and I'm greeted with this. All 3 wires are screwed into some kind of electrical joint thing. I've seen one before but i have no idea what its called. (its not an ISO connector.) From what I gather, red is a 12v constant, brown is earth and the other one is something to do with illumination. Also I need to put in a switched 12v and I understand that comes from the fusebox and is a brown/red wire? This is where the fun begins, as i don't really know what I need to wire it into. An ISO? or a something else? Then I would imagine I have to create my own loom for the speakers. Once again could I wire these up into a ISO connector and pop it in the back of the headunit? So yeah, I'm rather confused. Any help would be appreciated. Thanks
