Does anyone know the wiring diagram for a 1993 geo prizm's stereo? I'm hooking up a new stereo and not quite sure of the wire colors.

the store that sold the new radio has the connector kit
that you just plug in and wire up. (with drawing)
for cheap, preventing hack job to factory wiring.?

ok so you are hacking
here it is.
same wiring as a 1993 Corolla btw.
3 radios offered day 1, at TOY plant.

Cassette player works in 1994 Geo Prizm works, but all I get is static for AM/FM. Traced antenna from stereo to roof, and seems fine. Anything I'm missing. Thank you.

Get your hands on another am antenna....any one will do and attach it to your radio. If that clears it up replace the wire and antenna. If that does not then move to the radio as the suspect. The other thing I need to ask is how long have you had the car and has the AM worked on this before?

Check with a Volt meter for 12 v constant and 12v when key is turn it on and a ground . The rest of them is speaker wires, to check the speaker wires all u need is s AAA or AA battery. Put the wire on each end of the battery + and - with two wires you will hear speaker static then you know which speaker..
