Review on Metra 70-1721 Wiring Harness: Perfect Fit for 1998-2013 Acura, Suzuki, and Honda Vehicles by Jerry Chembola

Perfect match for my 2003 Honda Civic LX. If you are replacing your radio, you NEED this wire harness to actually connect the new radio to the wires that connect to the factory radio. However, you will need to solder or crimp the bare wires from this harness to the bare wires on your new radio (I soldered these, crimping works too and takes a lot less skill). When soldering, use shrink tubing to protect the exposed wires. It's also a good idea to tie the entire bundle together, as this will prevent the wires from bending or being stressed.
