On the bottom left handside of the diagram you will see the wires going into the amplifier in the trunk for your subwoofer - there are 8 wires - 2 for the + and - to the subwoofer - 1 for constant power - 1 for remote power (when you turn radio on) - 1 for mute- 1 for ground -
and the last 2 are the ones we are interesting in; one is for + input from the rear (+) speaker from your "new" radio - Yes! one of the (+) wires from your "new" radio will be going to the speaker it belongs to AND also to this PINK wire. And of course, the same goes for the (-) speaker wire from the "new" radio, connect it to the (-) wire of the speaker it belongs to AND to the BLUE (-) wire going to the Amp.
When you unplug your old readio and connect the harness for the new one.....there will be an extra harness from the old radio that won't be going anywhere - it won't be used by the "new" radio harness. This harness from the old radio will have six wires in it....THERE you will find the PINK and BLUE wire. That is it!!
Plug in your new harness, connect all the wires for power, ground etc....then connect the front speaker wires (match the colors) and when you do the rear speakers, connect one of the speakers to it's mathching color wires and the last speaker wires, positive AND negative....connect it to the matching color wires from the new harness AND also to the PINK (+) ang BLUE (-) wires from the extra harness from the old radio that you won't be connecting anywhere...when you do the install you will see what I am talking about.
I hope I have been cleared enough....let me know if you have any more questions....it's too confusing....I am willing to take my radio out and take some pixs...but that won't be until Monday...let me know
I tried your instructions here, but after connecting the pink and blue wires to the rear speaker wires, the radio said Miswiring. Any ideas?
