Look in the area behind the dashboard and see if there is an empty multi-way cable connector there, just waiting for a radio to be plugged into it.

Standard radio connectors usually have several wires on them, not just a "hot" 12 volts and a ground wire. The extra wires are there to connect to loudspeakers in the doors, etc. If you have such a connector then a car accessories shop should be able to sell you a standard plug and cable loom, along with a wiring diagram, so you can hookup the radio and its speakers correctly.

Every vehicle has a fuse that feeds "accessories" such as a radio. (Or radio/cassette or radio/CD player.)

What you need to find is that fuse i.e. its position in the fusebox, and the color of the wire(s) connected to it, so you can tap into one of them to power a radio.

Or, better still, if you can find a wiring diagram for the vehicle's electrics, there may already be a wire that goes from that fuse to the radio's fixing position in the dashboard, and from the wiring diagram it should be possible to find out the color of the wire.

Often, if you can get hold of the proper Haynes Maintenance Manual for your vehicle, it will tell you about all the fuses and give a wiring diagram too.

Another place to look is in the Owner's Handbook for the make and model of car. They normally list all the fuses but don't usually have any wiring diagrams or wire colors.
