Hello,

I am wonder if anyone knows for a fact that this port pictured on the AC compressor is a high side port I can use for diagnostics

I ask because I am doing a motor swap that involves me getting rid of the high side ports that were located on the AC manifold itself. I can survive without the port, but it would be nice for diagnostics.

Thanks.

The S and D on the manifold plate are your clue: Suction and Discharge. The port is on the suction side.

... therefore low side.

Thanks, didn't know what the S/D meant. I guess I'll just have to run without a high side port then.
