Does anyone know what the wiring color code for the radio harness, in particular i am looking for the light wiring because I removed my Pioneer radio which was installed professionally and they told me that I will not be able to dim or brighten the lights on my unit. As I posted before it is too bright. Today I removed my unit and found out that light wire is not even hooked up so I do not know how the unit is getting power to light it up?????
The unit is a Pioneer AVH-P4300DVD
2012 Mazda5 GT -- Clear Water Blue Mica
2012 Speed3 Touring with Tech Pkg. -- Crystal White Pearl Mica
The unit probably just uses full power if the light dim lead is not connected. This is the default for most systems as installation into older cars withouth the dim lead would mean no lights.
