I currently have a Sony Xplod deck (don't laugh) and am upgrading to an eclipse deck... will I need to buy a new wire harness and mounting kit, or will the one that is already installed work with the new unit?
the mounting kit should work the wiring harness im geussing you can splice the wires to make it work with the new head unit so yeah they should work
you should be fine with what you have just have to put the new cage in and splice the wires to the harness and your good to go!
