give it time, you expected to get a response in under 6 hours and this forum doesnt always have traffic like that.
i also did the swap, but i swapped from digital aka:
to what i call digital analog aka:
if you went the opposite way (switched from "digital analog" to digital), then you probably wont have use of the TPM anymore. my 2001 base deville displayed the slots for pressure, but i didnt have any sensors, so it didnt work, then i just bought a 2001 DTS which came factory the the "digital analog" cluster and when i scrolled thru options i did NOT see tire pressures listed.
heres what i did and you should at least try:
turn the car on
leave it in park
using the info (up,down) button scroll thru the options into you see something along the lines of features or personalize, and blue letters besides it that will say "off", push the "on/off" button and it will let you scroll thru options that you can personalize, when you get to "display tire pressure" turn that on, you should now see the tire presures listed
