A/C Help After 5.3 Swap

[lovesdunes]

Hi Everyone. Swapped a 5.3 from a 2002 Tahoe into our 97 2 door Tahoe. We have been driving the thing all over the place because it is so much fun to drive now.




But it's getting pretty warm out now so I really need to figure out the A/C.


The compressor is a Sanden 508.



I have the A/C Low Pressure Switch at the Drier and the A/C High Pressure Switch installed in the high pressure line between the condenser and compressor. I used this wiring diagram...




I also tried this wiring diagram...

Unfortunately it still does not work. I have been sick for the last two years and just now getting back to work on this project. I have been posting in a few different forums trying to get answers, but it feels like the people that have done their LS Swap and got everything working are no longer posting.
