I was directed to purchase the Metra harness chto-03 to work with the infinity system of my 2007 jeep wrangler JK. I followed the diagram and hooked up the radio and it blew the radio fuse 20 amp. I removed the radio harness double and triple checked the diagram and all was well and according to instructions. Hooked up again to have it blow. I would not recommend the harness and prob not the radio.
