I changed my head unit in a 92 ES300 about 3 years ago into a clarion double din. Now Im trying to sell so Im trying to put the stock unit back in. Everyplace I take it to can't do it because they say I need to have the original plug (harness???) to do it and lexus only sells that if you buy a completley new system. Anyone have any ideas or know where I can get the original plug that goes into the back of the unit? By the way. Its a stock unit that doesn't have cd changer controls.
