OK it it possible to buy a harness that connects the the factory harness that would inturn fit into a sony HU?

Or am i gonna have to splice wires to a sony Harness?

If you dont understand what i just said I dont blame you, i couldnt think of the right words, but if you dont understand ill try to explain better.

 

your new sony head unit will come in one of two configurations....

either
1. it will come with a harness that plugs into the head unit itself. OR
2. the head unit will just have wires coming out of the back of it.

either way...what you do is get a harness for your car. you can get them at LOTS of audio places....even wal-mart. Wal-mart is the national distributor for Scosche. the scosche part number is MA-03. they most likely won't have it in stock...but they will special order it for you if all you have is a wal-mart around. the METRA part number is 70-7903.

then you match the wiring from the harness that comes with the Head Unit to the harness you get that matches your cars harness and connect them together...NOW you have a harness that is either
1. a harness that both plugs into the back of your deck AND into the stock harness of the car....OR
2. you have a harness connected to the back of your deck that plugs into the harness of your car...

either way...you are set to install the head unit.
