Saitek TPM - Re-assign throttle to prop

I have a TPM by saitek but in my cockpit it is placed just under my right knee and the (black) throttle is touching my knee when pulled out, so I want to disable the throttle control and replace it by the Prop (blue level) so it is next to the mixture (red level) I would eventually paint my prop knob in black. (don't need prop controls as C172 does not have any on most airplane)

In the game setup (saitek) they have the 3 (T-P-M) displayed and it is for adjusting levels but not assign controls.

How do I assign controls to make like the setup above working?

Solved, was easy just go in FSX control settings and assign Prop as Gas.
