The most helpful suggestion would be sell the car and get a new one that has a radio, who would want a 17 year old car in the first placeHow do I wire in a car stereo into a 1991 Toyota Previa?
Goggle the make and number of the stereo. The live and earth should e obvious. The neutral in normally blue or black and white striped. Speaker wire come in 2 with each set being the same colour. Don't diy this unless you know what you are doing as you could blow the stereo if no speakers attached. Luck.
If you have a multi-plug you can buy a kit to match to your new stereo. If you just have loose wires then look for a permanent live for your radio memory. Pre-ignition live for power. An earth wire{usually black) And speaker wires. There could be between 2 and 8 for speakers and they are usually paired by colour i.e. grey and grey with a different coloured stripe. Blue and blue with a different coloured stripe etc. Pre-ignition is the key position just before you get ignition lights.How do I wire in a car stereo into a 1991 Toyota Previa?
