Wendell, my 89 already had rear speakers and harness as well as an aftermarket fader, which I have now removed.
The easiest way to see if you have rear speaker wiring is to open your rear trunk lid and see if wiring is going up into the rear speaker housings through a round hole in the bracket of the hinges.
If not, you need a harness. One thing I have been doing this winter is eliminatating all the existing speaker wiring by bringing the radio outputs back to the trunk and wiring monster cable wiring from the trunk to the front and rear speakers. In the trunk I mounted a quad 80 watt amp and a graphic equalizer with front to rear fader. Once set I don't need to get to them while riding since I still have volume and tone controls in the radio itself.
If you want details, just ask.
