the motor is a 2002 don't think that matters

The one pictured above is not the correct part for the T-45:

It T-45 sensor looks like this (it's a Standard SC37):

When I did a search for a 98 Mustang GT, I got 2 sensors, one for Speedometer and one to ECM, your pic was to speedometer, the one with my pic is to the ECM, would that cause a failed code?

OSS and VSS are just different names for the same thing--on the T-45 it's gear driven, on the T-3650 it's a hall effect sensor.

So, that is what I need to change to fix my code and pass inspection. P0500 was the code that failed inspection. Okay will get and change it and hope it passes, thanks again. Just would of never thought it would be that sensor cause my speed-o-meter works.

There are other problems that can affect the quality of the OSS signal, to properly check it you need the Ford IDS (Integrated Diagnostic System) or some other system that can access the VSS PID.

Here's what the shop manual says about P0500...

What PCM are you running, the '98 or the '02?

I ask because the '98 VSS produces 8 pulses per sensor shaft revolution (as it is gear driven the pulses per tranny output shaft revolution will be a function of the gear ratio).

However the '02 PCM will be expecting 12 pulses per transmission output shaft revolution unless it is reprogrammed--this could perhaps throw the P0500 DTC???
