If this has been covered already sorry about that, please post a link to the thread. Ok here goes... I got a pioneer head unit in my truck now and I had to buy a new harness for it when I had it installed. I now have an extra head unit that is a sony xplod I'm not sure the exact models. do I need a new harness for the sony or should it plug and play into my current setup?



See tag for truck year etc

 

The old harness will work you'll have to wire the new deck into it.
