I want to replace the existing OEM radio with an aftermarket CD player/Radio. The only wires that I can identify are the Ground, Batt, and Acc. I have tried using a 9 volt battery to locate the speakers but can't get any of them to make a sound.When connected directly to the rear speakers from the trunk they made a loud sound. When trying all the possible combinations at the connector plug I get nothing, although they work fine with the orig radio.This is not the first time I have installed a radio in a car, but it is the first Toyota that I have tried. The connector is original factory installed as is the radio. Any help will be appreciated

go to installdr.com and look for the wiring diagram. I hope this helps.
