Any chance you could post a photo of these wires? Also, do you have the vulcan or duratec engine? Vulcan=alt. is up top and easy to access. Duratec=alt. is low and difficult to access.
2000 ford taurus altenator wire harness
Where do the 3 wires coming out of the altenator wire harness go???

They go to the alternator plug but your post is confusing. If they are cut then look for wires of the same color in the harness or plug.

I have looked. I have found 2 of the wires but it is a different altenator and plug.They go to the alternator plug but your post is confusing. If they are cut then look for wires of the same color in the harness or plug.

I have the harness with 3 wieres coming out of it. I need to know where to wire them to. On my engine or wherever they go.They go to the alternator plug but your post is confusing. If they are cut then look for wires of the same color in the harness or plug.
Whatt years are your car and alternator because alternators and harness changed in 2002 and older alternators won't work on the newer car.
Just wanted to shed some light on this from my visit to the local JY yesterday. They did not have a 2000 Taurus (Vulcan) on hand, but had a 2001 Taurus (Vulcan) SE. Because Rockauto shows the same alternator for both years, I took a close look at the alternator wiring. The harness leading to the alternator plug was a 2-wire. The plug had the capacity to utilize three wires and the plug receptacle on the alternator also had three prongs. However, the middle prong was not being utilized on this vehicle. So, I am confused as to why your 2000 has 3 wires within the harness...and, what does that third wire do?
Just checked it on my 2000 SES Vulcan: it indeed uses only 2 wires, the two outer ones. The one numbered 3 on the connector (the closest to the alternator output cable) is rather thick and colored Orange/LightBlue. This is the one that should go to the battery through a 30A fuse (according to the schematics in the Haynes Manual). The other is numbered 1 on the connector and is a thin wire colored LightGreen/Red. That goes to the Battery indicator in the instrument cluster. I assume it just carries 14.5 V if the alternator is working, so that the light goes out.Just wanted to shed some light on this from my visit to the local JY yesterday.

So for the alternator to work, it only needs wire 3. Note that the alternator has no permanent magnet. The regulator controls the current through the rotor (and thus the magnetic field) in such a way that the output of the alternator is 14.5 V irrespective of the RPM of the engine (high current at low RPM and low current at high RPM). Without wire 3 attached, there is no magnetic field and the alternator does absolutely nothing, other than happily rotating.

And what color was the wires?
Maybe you realized it but you can't use a two wire alternator on a wiring harness that has three wires. Up to and including 2001 are different than 2002 to date. the older models used an internal regulator and the 2002 and newer uses the PCM to regulate voltage.
So my car is a 2000 taurus. Should i have a 2 wire harness or a 3 wire harness?Maybe you realized it but you can't use a two wire alternator on a wiring harness that has three wires.

All I can confirm is what Architect stated...that there should be 2-wires for your year car. One being Orange w/Light Blue stripe and one that is Green w/Red stripe. They utilize the outer two connector prongs of the plug. If your car has 3 wires coming out of the engine harness, then I can't be of much help explaining why that is the case. BTW...I have the 2-wire plug off the '01 Taurus w/Vulcan engine with about 6" of wiring for splicing if you want it. LMK.
That would be awesome. Yes i would love it to get my car running. It has been broke downfor over 2 months.All I can confirm is what Architect stated...that there should be 2-wires for your year car.

I think the third (middle) wire is used on later Taurus models by the PCM to monitor the status of the alternator....

...
Somewhere (I can't find where that was) I read the middle pin is called FREQ and
2006 PCM pinout
calls pin 20 of the PCM "Generator, signal 2, monitor" and says the color of the wire is GY/YE which I assume stands for Grey + Yellow stripe.
For for your 2000 Taurus all this can be ignored. Mine does't even have a middle wire coming out of the connector.
