For the radio I know there are several different harnesses depending on the speaker set up.
3 speaker (stereo) dashes use a different harness than the single speaker (mono) dash.
There is a second harness that runs to the rear of the car. Stereo has wiring for 2 rear speakers, while mono has wiring for only one.
However these harnesses never connect directly to the main harness, they connect to the radio, speakers, crossover box, fader.
No matter what option you selected the main harness connection to the radio was standard (a red and orange T shaped connector for the radio power and light).
