That light indicates that it is time to replace your air filter. After replacing the filter you will want to reset the lamp. On the air filter housing is a filter indicator. It is a small (2" round) cylinder with red, yellow and blue colors on it, as well as 2 wires. Push in the rubber yellow cap on top of the cylinder until you feel a snap and see the yellow plunger in the cylinder move. This should reset the light.
I hope this helps

Note: using an optional snap on wire harness adapter will simplify the wiring. Most snap on
wire harness adapters have already converted and color coded the wires from the auto
makers in dash wire harness to match typical aftermarket radio wire colors.
** The wire colors listed in the chart above are typical for these vehicles during these years
but may not be the exact colors for this vehicle. This is another reason to use a snap on
wire harness adapter. **

To find your speaker wires check the color of the cord behind each speaker than match it with the same color in the dash.
or the easy way is to use a normal 1.5v penlight battery and try each speaker cord behind the dash and listen to which speaker give off a crackling noise so you can get the balance on the cd player right.
If u trying to find power in the car and don't have a tester than get a 12v light or bulb join the negative to the body and push the positive wire into each one of the holes in the factory plug in the dash one at a time until the light comes on. That is your positive the rest is easy. (DIY guru)
