Jumping High Pressure Switch 850 1993

This is for my 93 850.

I would like to jump my high pressure switch to see if it is the culprit in my non functional AC. Already tried the low pressure switch. It also won't take any more freon. But when the compressor is jumped to force it on for about 30 secs, the cold pipe does not get cold. They both just get warm. Will be buying a manifold gauge set soon to do the AC on my other car, so I thought why not get the 850's going while I am replacing the noisy compressor on the other car.

There are 4 wires on the high pressure switch and I have no idea which ones to jump. Any help would be appreciated, although I don't think it is the high pressure switch.
