2003 Ford Taurus SES stereo install?

I'm trying to install an indash stereo with Bluetooth and such into my Taurus. I got the 18 foot long harness to run from the trunk to the dash but the harness only has 9 wires! (8 wires for all 4 speakers, and one wire to connect to an amp to control the amp) it doesn't have a power wire! What am I supposed to do? The stereo has a red wire to connect to constant 12v supply terminal and red to connect to terminal controlled by ignition switch but again, the wiring harness doesn't have those!

Does the serpentine belt breaking cause an alternator to go bad or vice versa?

Just the other week I had the power steering pump and serpentine belt replaced on my '96 Ford Taurus; since then my car started making some grinding noises particularly when I was idle (The car drove completely ok with the exception of the noise) -- After doing some research on the net I found that its a good possibility that the alternator's bearrings went bad. Do you think this caused my serpentine belt to break the other week? Or do you think that the serpentine belt breaking caused the alternator to go bad?

I have a 2001 Ford Taurus Lx, it sputters and hesitates during acceleration! It doesn't go pass 25 mph but will reach 5 rpms! Changed spark plugs and wires! Also changed coil pack! Both converters are working properly! Check engine light is not on! Doesn't run hot! Tire pressure indicator comes on though! Not sure what my next step is! I need help!

Oil Change: Right Motor Oil, Wrong Oil Filter?

I drive a 2001 Ford Taurus SE, I [attempted] to do my oil change today.

I have been using Royal Purple 20-400 (oil filter) AND Royal Purple 5W-20 synthetic oil.

After I drained the oil from the oil pan into the catch pan, I realized that the new oil filter that I purchased was the wrong one. As stated above, I was supposed to use Royal Purple 20-400 with my car, the one I purchased was 20-820. I just ended up leaving the old one on there, though poured in the new synthetic oil. I have been approximately 12K miles on this oil filter, however, the highest potential is 14K.

That said, when I receive the new 20-400 in two days, could I just use the oil that I just recently put into my car?

What effect(s) (if any) could this have on my vehicle? Is there an that I should be worried about given this potential scenario?

What do I need to do to increase the power in my car?

Hey everyone I'm coming to you with a simple request. I want to put in a little more power to my 2012 Ford Taurus SHO and am looking into a bigger intake and a better sounding exhaust with down piping. I'm new to modding my car and am seeking some guidance on making sure I do this correctly. This is my everyday car so cutting corners is not an option and I would like to do this right the first time and enjoy the new changes.

With these upgrades in mind do I:

-Need to swap software so I can reach the full potential of my cars engine?
-Change the octane in the from 87 to something higher?
-Swap spark plugs?
- Etc.

I hate surprises that cost money to fix so any help is appreciated in doing this.

I only ask the your responses be respectful.

Can a rookie officer ask his department if he can drive an suv unit?

Hi. I'm 5'9" and 253 lbs. I'm trying to be a cop when i graduate. The problem is that when i took a ride of the ford taurus, it was too small and tight inside. I know that the ford police interceptor is based on the taurus so i'm really worried that. Can a newly hired officer ask them if he can drive an suv instead of a sedan if they have suv units?
