Review on Metra 70 7003 Wiring Harness Mitsubishi by Corey Katchem

Originally I accidentally bought an original aftermarket speaker wiring harness (I learned this the hard way, it's a good idea to take out the factory radio and check, because it will NOT work if there is a factory amp in your car). If you unplug the factory radio you can see that on the back there is a large black wire (which I didn't connect to anything) and then a smaller black wire that goes to the radio (it goes to the amp if you don't have it do' Don't use this wiring harness (70-7003) to convert to RCA plugs and plug into the back of the aftermarket radio, you will have no sound.) There is also a basic wiring harness that plugs into the factory radio, only 4 wires coming out of it (a telltale sign that there are no speaker wires in the main connector) Good luck to you dyers, I hope this helps you avoid my earlier mistake!
