Make sure that the blade on the end of the shaft is in the slot on the back of the TPS. you have to put the TPS on that blade then rotate it to line the bolt holes up.

I have checked the blade and it is set in the slot also the RPMS did move from about 400rpms to 800rpms after the new install

What was the part # of the TPS you used ?

Kinda odd your rpm changed since the TPS doesn't control the idle.

I will look in to using the sensor you found if this doesn't work though I'm out of ideas ... is there anything else that could cause this issue ??..

Thank you for your advice I really appreciate it

My money is on the fact that you ordered a TPS. There is no such thing on a diesel. It is referred to as an APS, or Accelerator Pedal Position Sensor. Coupled with the fact that you had to change connectors (APS sensors are directly bolt in/plug and play, with factory wiring, you never have to change connectors). Between the sensor and your connector splice, I'd bet the wiring is wrong and also the sensor is wrong.

Before I messed with the wiring I would install the correct sensor, and then if it still doesn't work, investigate your wiring.
