Just wanted to know if I could use the Metra style adapter kits to make it work? I got one for a good price and would like to make it work. My thought are to get this TOYOTA 4Runner 02 03 04 OEM Reverse Radio Wire Harness | eBay and this Radio Install Harness Toyota Lexus Stereo Plug JBL amp | eBay I have searched a bit but the JBL Scion threads are limited. Thanks
