That test was to test the relay circuit and acc panel to seek ground..
Unplugging both the temp and throttle sw eliminates them [ they ground to stop comp]
Grounding 10 at relay eliminates the comp pressure circuit/panel
When you jumper 5 to 7 , you are bypassing the relay circuit..[simply jumping the load contacks of the relay]
So, you are down to relay /modual input fault

You have the schematic there ?
I am not sure if I am on the right one ....
