    What can i use this information for? I am trying to connect a radio and i have the color guides for that too. Do i just make them match up and it will work?

    Hi there! I’ve a problem! I’ve a Pionner DEH-2200UB and when I shut down the ignition and remove the key, the radio have a memory shut down! Whats going on? Thanks for any explanation.

    Jorge, you may have mixed up the battery constant and accessory switched wires. The battery constant always sends power to the radio to save your radio stations and other audio settings. The accessory switched wire sends power to your radio only when the key is in the ignition and your 1998 Toyota Corolla is on. Check your wiring and make sure the correct radio wires are hooked up to the correct wires on your factory harness. Hope this helps. Good luck with your 1998 Toyota Corolla radio installation.

    Having a bit of trouble, wired the 1998 Toyota Corolla stereo up and now the lights for the climate control no longer come on, however did notice 2 extra wires, a green one and a white one with a green stripe. Any ideas? Please and thanks.
