Hi, I have a 99 sable with a stock head unit w/ digital climate controls. I have a Haynes manual, but the wires are all off. I can't figure out where to put the Remote turn on either. I bought an output converter, and can't figure out which wires go where? The wires going into the rear speakers aren't even in the wiring harness in the back of the head unit. please help!

The wires you are looking for would be at the RCU in the trunk. The head unit is really nothing more than a remote faceplate. The actual head unit is called the RCU and is located in the trunk, or in the wagon, behind the spare.

Probably have to do the same thing i did... when i bought the aftermarket headunit, i got home and the color coded wires didnt match up. When you buy a new headunit here are little wires sticking out of the back for the power, remote, illumination, speaker, ground, ignition, blah blah blah... and you need a wiring harness to show the correct coloring for those wires. If you go to metra.com or a car audio shop u can get the wiring harness that attaches to those wires on the back of the headunit and it will connect directly to the harness that goes to all of the speakers in the back.(there are 2 harnesses for audio in those vehicles, one that goes from the radio to the "brain" in the trunk, then a harness from the brain to all of the speakers. So with the harness you will just be connecting those 2 harnesses together wihout a need for the "brain" and may take it out as i did. But in order for the actual am/fm to work you will neex to get a car antennae extension cable to run up to the headunit for your year i believe

If all you want to do is add a sub, all the wires you need will be at the RCU in the back. Don't mess around wit the head unit/faceplate. The connectors at the RCU are similar to those found on other Ford models, and the color codes should be the same.

Of course there is a n RCU in the trunk. Go take a look. All Gen3 Taurus models have an RCU in the trunk. Like I told you before, all you speaker wires are going to be at the RCU.

    start checking out auto zone etc.for wire diagrams. also if you do not have a strong enough loc which is the line output converter which you need some thing like this cause high poweramp is what you got for the stock amp. may not be as high powered as a after market set up but as stock goes it is high power.

    that is what i suggest for the loc also if you got a loc hooked up to the rear speaker wires then all you got to do is turn the left or right output up on the loc. then match them to the amp level control. do not forget the remote turn on wire. if you skip this step the amp will stay dorment and not turn on with the use of a loc.
