@azzx If you want to pin this info to your OP:
If you have a cable harness coming out of the existing TBC module with a tag saying PN: 68601443AA (the part number tag for the harness can be seen from under the rear seats), you only need part numbers:
68569520AB: TBC Module
68618899AA: Switch
And for the dealer to program your VIN.
If you don’t have that cable installed, you’ll need the full kit along with getting it added to your VIN.
The full kit is PN 82219240aa, which is on back order, includes the above 3 parts (cable, switch & module),
