Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Just trying to understand your question here?
Have you fitted a replacement radio & now it doesn't work in the "accessories" position? Or the radio did work whilst in the "accessories" & now all of a sudden its doesn't?????
See attached Holden Eurovox wiring guide
Hi, I have tried to trace the rear speaker cables back to the stereo with a meter and physically however they seem to go past it, do you know where they go?If the old VK Eurovox radio worked on "acc" then the new 1 wil work as well. I would have it at a guess that it's wired up wrong or blown fuse?????. I've attached the factory VK stereo wiring diagram for your reference.
1st: Check fuse number 14 as that is the stereo fuse.
2nd: Pull the new head deck out and check for 12V + (power) on the original factory "yellow wire" in both "on' & 'acc" positions.
3rd: Check for constant 12V + (power) "orange wire".
4th: Check you have a good ground - "brown wire".
Good luck
