I think you will have some serious issues with this conversion.
The "touch shift cars" use a completly different networking system
for the transmission controls which ties into the cluster.
The vehicle body harnesses are different from 99 to 00' and so
are all the other related can operated systems.
The floor shifter is actually a control module and communicates
info to the transmission ecu and valvebody.
The engine ecu is also modified to communicate with the shifter.
The 99 used a brake pedal / ignition switch park interlock cable
which ran from the pedal to the rear of of the trans.
On the 00', the stop lamp switch is used to activate a solenoid in
the shifter.
I am not trying to rain on your parade, but this may not be
a plug and play setup.
Sorry.
