There is basically no proper information about wiring and using these boxes online in english. The wiring  diagrams from Renault are either unusable (they use the color of the connectors in the car to identify them... If you just have the control unit without the car you cant follow the diagrams...) or just wrong (They tried to fix the colored connector problem in later wiring diagrams BUT numbered the connectors wrong). 

Lets fix all of that.

- First let us understand how to use the synthesizer box. 

There are 2 versions of controls for the system. I have auto translated the general function description for both versions. Its not perfect but it tells us everything we need to know about the function of the buttons.

Phase 1 controls (1984-1988):

Phase 2 controls (1989-1992):

Work in Progress........
