culshaw 1 Posted April 1, 2019 (edited) Has anyone managed to rip out an entire audio harness? My stereo has never worked and no matter where I try to test for voltage I get nothing, so planning on ripping it all out. Also if anyone has, where have you purchased from? Thanks!

fendervg 32 Posted April 1, 2019 (edited) I'd say it won't come out as a single harness - you'll have 8 x speaker wires, +12v switched from ignition, +12v from battery, earth, ariel power, speed sensor, illumination, maybe phone mute and more if you have a CD changer. These will all go back to different places in the loom. You should be able to identify the original wires for power if you dig deep enough - often someone will have hacked into it and fitted a connector. The attached (in german) is for the Gamma IV layout in a Passat of similar vintage - but it will give you the wire colours with a bit of Google Translate - e.g. blue/white speed sensor in spoiler control module, brown for earth, red for ign live, etc. I'll see if I have anything else useful. stromlaufplan_gamma4.pdf Edited April 1, 2019 by fendervg Quote Share this post Link to post Share on other sites
swiftkid 1 Posted April 1, 2019 I don't know the back story on this but hopefully his will help: From the CE2 webpage it says these are the following wires. Red - Permanent live Q/3 Brown - Ground/negative E/5 Brown/Red - Switched live (ignition) H1/7 Grey/Blue - Instrument panel lighting Q/6 Blue/White - Speed signal for automatic volume (only used on VW oem units AFAIK) http://www.a2resource.com/electrical/CE2.html Check power at head unit, red should be constant and brown/red is switched but probably a yellow wire by the time it gets the head unit. If nothing, check at fusebox, if you get something there check resistance and hopefully find you've just got a broken wire. Also, when checking power earth to an earth point not the radio earth just incase it's a bad earth Quote Share this post Link to post Share on other sites
