G'day.
After removing the factory (GLS) radio, There is an additional plug which I am not sure where it goes first there is RADIO ==>Plug=>Wires==>Plug==> which makes for easy removal to solder (which makes me happy), however in this little middle wire section there is a single yellow wire that is next to the front speaker wires, it has its own bit of conduit and runs out under the dash, steering column and into a little plug in the fuse box. the plug in the fuse box looks like it could accomodate about 6 wires, but there is only this one.
It is not a part of any other wiring (not cable tied or taped to main loom) so it looks like a bit of an after thought.
Any ideas on what this could be? - The Yellow Power wire is there so its not that, and thoughts on which way signals travel along it? (i.e if from car to stereo then I won't worry about facilitating it in my new install)
Thanks
Dave
