so whilest i was doing some research on the radio. i found that it is an infinity III and that the clear connector is some antenna thing. and that certain ones have the option to add a separate cd changer. it was made by alpine too. chrysler wired the factory amp from the radio through the factory wiring and ran the speakers(front and back) through the amp. looks like i now need to figure out what wire is what on that direct splice in i have.
btw this is the radio i have.
the only thing i don't like about this radio is the eject button is electric, not spring loaded like my old radio.
i also found that it came in the 87 new yorker, lebaron gts, daytona's, voyagers, and a couple other cars.
i thought that some of this info might be helpful to others. the reason i went these radios is because my alarm is broke and i still want to be able to run an amp in my truck and have the factory look without adding extra wiring and such.
