Sorry man I been busy, but the VSS wire has to be tested using AC voltage on the meter and the reverse wire is tested using DC, sorry I wasnt clear.

If you are not getting a clear reading make sure you have a good ground on the black lead off the meter, that could be why you are only getting a 8 volt reading for the reverse wire.

Does the meter you are using have auto ranging?

 

yeah it does, also I called 2 local audio shops about the location of those wires and they same both of them should be located at a 10-pin PCM??? where is that? I looked on the left side of the radio and yeah I saw a orange-striped white wire and I saw the pink-striped black wire going deeper into the dash. Could those be the same wires also?

 

Could be but they could be something different.....The orange/white is in the pass.kick panel....I know that for a fact bc I want there on a few different mustangs besides mine for it.....

When you tested the VSS was the car moving? You hitting the gas then braking?

The reverse wire to test that put the meter on DC voltage red lead to the black/pink and the black lead to a GOOD ground....When the car is not in reverse the wire will test 0 volts, then with the car in reverse the wire should show 12 volts or right around that voltage(11,11.5,and so on)

 

the VSS wire went up to 1 stopped and turn the wheel thats when the meter went up to 1 when I was on the hwy it was always at .015-.020 at 70mph

 

The meter your using doesnt have auto range does it? And you were on AC right?

 

thats what kind of meter I have and yeah I was on ACV:

Yeah your meter is auto ranging so.... there could be 3 things that could be wrong.

1. you are testing the wrong wire.
2. you do not have a good ground on the black lead.
3. batteries in the meter are going dead.


I take pictures tonight and post them.

What about the reverse wire did you find that?

 

I found one in the same area (passenger side kick panel) and tested it that's where I got the 8 volts from. The VSS is suppose to measure how fast your going on the navigation right? Hey I know its a lot, but thanks for your help I didn't think anyone would respond to this post at all I'll test the VSS wire again and hopefully I can put it on video

 

Well did the wire show 0 volts then go up to 8 when the car started to move, then it drop back to 0 when you stopped? If so then "bingo" you found the right wire.

Here is what the VSS wire does:
Vehicle Speed Sensor (VSS)
In addition to the standard power and ground leads, remote-mount navigation (and even some in-dash units) systems connect to a vehicle's Vehicle Speed Sensor (VSS) wire. Your vehicle's cruise control uses the VSS wire to determine the vehicle's speed &mdash it serves the same function for the navigation system. (Don't substitute the tachometer signal wire for the VSS wire &mdash the tach signal wire sends pulses as long as the engine is running, even when the car is sitting still.) The VSS wire sends a series of pulses (from 800 to just over 1,000 per mile) only when the vehicle is in motion. If the VSS wire is not hooked up, the navigation system will not realize that the car is moving at all, and will be unable to track position.(This is from crutchfield and is from 2003)


If the VSS wire isnt hooked up it will still give you the speed bc it will calulate it throught the GPS antenna but the reading will not be as accurate.(Few MPH off)

 

Sh*t Jay for some reason I cant get the picture to upload, but the white/orange wire is in the black plug in the pass kick. The black plug is in between 2 gray plugs....

The PCM is located above those 3 plugs, high in the kick panel.
