gbhrps Posted November 14, 2016 Share Posted November 14, 2016 Gary, I assume you are trying to put an aftermarket radio into your es330, and I assume you're going to use the same speakers that are presently in the car. That said, you need to get a harness adapter to go from the Lexus dash wiring harness to your new radio. Basically you remove your old radio from the car and unplug it from the dash wiring harness. Then you plug the wiring harness adapter onto the dash wiring connector, and plug the wiring adapter into the back of your new radio. Go to the Crutchfield.com and type in the search window "car wiring adapter", then scroll through the products until you find the Lexus adapters. Or call the telephone number listed on the website and they'll tell you what you need to connect that radio. Good Luck! 1 Quote Link to comment Share on other sites More sharing options...
Adam S Posted July 12, 2017 Share Posted July 12, 2017 I think I formund the amp in the pass side kick panel. Remember to also hook up the wire that turns on the amp or you will get no sound. I also found out that all the speakers are the pre amp 1993 ES300 Quote Link to comment Share on other sites More sharing options...
