Installing Pioneer AVH 4000NEX with Euro Motorsport Double DIN

[jpc763]

I am in the middle of updating my head unit. I purchased a Pioneer AVH 4000NEX and the Euromotorsport install kit. Everything is going pretty well but I have stalled out with the wiring harnesses.

This is the Euro Motorsport Black plug


This is the Euro Motorsport Red plug


This is the Pioneer wiring harness


There are corresponding wires for most of the black plug. The only one that I am concerned about is the blue one. The Pioneer blue one says "System Mute Control".

There is a blue wire on the red plug. Is that the one (it has a white stripe)?

The pioneer did not come with any wiring description.

Any suggestions?

Thanks, John
