I need the wiring diagram for my 2015 Ford Focus Stereo. The colors! Which wires goes to which speaker?

I need the wiring diagram for my 2015 Ford Focus Stereo. The colors! Which wires goes to which speaker?

Found this on a Ford blog, seems legit

Left Front + WHITE
Left Front - WHITE/BROWN
Right Front + WHITE/PURPLE
Right Front - WHITE/ORANGE
Left Rear + BROWN/GREEN out of the HU, WHITE/GREEN back to the speaker (color changes at this connector)
Left Rear - BROWN/YELLOW
Right Rear + BROWN/WHITE
Right Rear - BROWN/BLUE

How do I remove my 2016 Ford Focus se stereo because it seems as thought the piece to get at the bolts is fixed in the middle but not the sides.

Does the 2017 focus 4" radio use the same wiring as the 2015 focus 8" radio?
