having installed an ipod to car adaptor, i can tell you that the factory radios do not have an RCA plug. the adaptors work by plugging into the cd changer port. they do make an additonal adaptor so that you can run both the cd player and mp3 player thru the port, check and see if your unit will work with that or not. if not, then there are a few options. the cheapest would be to see if someone on the pt forums has a factory unit that can be used with the adaptors. sure there are lots of pt owners that have changed out the factory stereo and would be willing to sell cheap. the second option would be a new head unit. a year or so ago when i was looking into this, i found only a few brands made stereos with the RCA plug, and that they seemed to start at over 250 bucks. not sure if that has since changed. but whatever you do, it will sound much better than the FM modulator. as for the back of the stereo, i think it may be easier to just pull it out then to try to find it online, only takes a minute. search this forum to find directions for removing the center console and radio. good luck and let us know what you decide to do!
