The ambient sensor prevents the A/C compressor from engaging at low outside (ambient) temperatures. I think its set around 40*. Contact terminals should be closed (0 ohms) when measured with an ohmmeter above 40* plus or minus a few degrees. Put it in the refrigerator for awhile to test contact opening. I may have the plug you need in one of my spare harnesses. Does it look like this?
