Stereo Upgrade - Day 1

Since I am going to keep the stock head unit I will need to convert the high level speaker output to low level. High level is usually the amplified signal that goes directly from the stereo to the speakers. In order to add an amplifier you will need to convert it to RCA preamp outputs (low level).

I went to Walmart and picked up a Scosche Hi/Lo Line Level Interfaces SLC4 for $17.77. It is a little box that taps in your exiting speaker wires so you can hook it up to a amplifier.

What I have done here is take out the dash so I can access the stereo wire harness.

Here are the two main two harness with the high level out puts. Just look for the following wire as labled:

Left Front Speaker Positive Wire (+): Blue/White
Left Front Speaker Negative Wire (-): Blue/Red
Right Front Speaker Positive Wire (+): White/Black
Right Front Speaker Negative Wire (-): Blue/Black
Left Rear Speaker Positive Wire (+): Light Blue
Left Rear Speaker Negative Wire (-): Black/Yellow
Right Rear Speaker Positive Wire (+): Orange/Blue
Right Rear Speaker Negative Wire (-): Red/Blue

Tap in to each of the wires and hook it up to the Scosche SLC4.

After you are done it should look something like this.

The airbag light started to blink after I was done putting the dash back. So I went online and did a search, and found out the in most cases if you do any work on the front dash or anywhere near airbags, it will trigger some alarm. So instead of taking your car to the dealership to get it reset, this is what you can do. I have reset the airbag sensor many times and it works flawlessly.
Blinking air bag light

Usually this happen when one take of the radio bezel to do some work, but if yours just come on for no reason you might want to take it to the dealer.

Try the reset procedure first to see if it help.

1. Turn the key from off to on.
   
2. Watch the airbag light closely. It will stay on for a few secs. and then as soon as it blinks off (the start of the flashing), turn the key off instantly.
   
3. Count to 5 (1 Mississippi, 2 Mississippi . . . .)
   
4. Repeat steps 1-3 two more times until you have done the cycle three times.
   
5. Now turn the key on and watch the light. It will start blinking in a different, slower manner. This is diagnostic mode. You can watch this for a little while, no hurry.
   
6. Now turn the key off again, Count to 5 like in step 3 again, and turn back on. If the procedure worked, the airbag light will not be flashing.

If it does not work the first time, just repeat the steps again.
