S52 A/C & electrical q

[etxxz]

I'm running an OBDII s52 setup which is already wired...mostly. My question is how would the A/C compresor turn on? what/what relay does the "FROSTY" button activate? where?

is this something that goes through the C101/X20 plug? (pin 4 on the X20 is a/c comp control idk what it means)

a/c controls are in the body harness. the plug should be near the passenger strut tower. plug #5 seems to be for an automatic trans.

I located the plug that you're talking about, i had didnt mark it when i removed the m20.

Now the problem is the following: None of my climate controls are working, not the 4-speed fan, the incar circulation, or "frosty button" are turning on.

i checked all of the fuses and they all check out. Any suggestions on what the problem might be?
