What does pink and orange wires usually mean? I'm thinking orange is illumination but not 100% sure either.

 

well it depends on what car or HU....if its on the aftermarket HU then orange/white is the positive illumination and plain orange or orange with black is the negative input(depends on the HU)

when it comes to the cars then it depends...on all GM cars orange is the accessorry wire...on our maximas it can be factory disarm/arm or power lock/unlock(depends on the year)....now as for the pink wire....i know that pink is the wire for hazard lights in 2002-2003s and when it comes to audio its RR speaker(+)

if u could be more specific as to what u need then would be great....

good luck

 

Is illumination necessary?

 

not really.....all it's going to do is just dim your HU a bit when u turn on ur lights.....that's all...it's up to you if u want that or not....

 

pink I think is mute
