I'm installing a new sound sysem into my '93 940 turbo sedan, and i am just wondering if anybody out there knows the color coding for the wiring, i don't have an amp. i have gotten started, and think it goes red/green-pos. bat. orange-ignition. brown/brownwhite-left front speakers. grey/redgrey-right front speakers. white-light dimmer. green-power antenna. If anybody knows the rest or has a correction i would appreciate it. thanks

Did someone cut off the factory plugs before you got it.
If not why not just buy the adapter harness to make it alot easier to install.
