There appears to be a short internally in your steering wheel.

Test it with a multimeter to work it out but often the yellow wire if for a electric aerial

The service intervals are normally every 50,000 Klms, but having said that you can tell by checking the dip stick. If the color of the oil which is red, has gone to a darkish brown color, it's time to change the oil.

The battery is charged by the alternator which has computer (PCM)controlled voltage regulation, this makes for a much more precise engine and stable voltage for the engine management system.

head down to your local auto store and you will be able to pick up a wiring harness adaptor. you wire your stereo to this adaptor then you simply plug it into the wiring loom. no damage to the loom so if you ever need to reinstall the standard stereo its just an unplug and plug back in. its extremely simple and colour coded so there are no mistakes.

should be a red for hot black for ground yellow for memory and blue for amp remote. the rest of wires are speaker wires. match wires with car radio has a pair of wires for each speaker. like tan for positive tan with stripe on it is ground.
