2008 F430 Tire pressure monitor sensors

I have a 2008 F430 coupe. If i buy a whole new set of new tire pressure monitor sensors, do I need to program them to make it work? if yes, how do you program them? The 2008 comes with this grey colored sensors, where the 2005-2007 comes with the orange ones. I was told that the orange ones operated in different frequency than the grey ones. Any input will be appreciated. Thanks

 

Do you have any pics to post?

 

Did we speak this morning about your car? Indeed, they are different frequencies. Here is the grey one:

You cannot mix them. If you have an 08, you must use the later ones.

 

I'm stumped?

Why would you want to buy a new set?
What difference does it make if it's orange or grey.
They sit inside the wheel underneath the tire where you will never see them.

 

I bought a second set to use on another set of wheels. color denotes vehicle model year.

 

They operate on two different frequencies. The receivers (in the wheel wells) can only pickup the signal from their intended sender frequency. People buy new ones if they don't want to disassemble their old ones any yank the senders when they install aftermarket rims.
