Purchased a replacement COMPRESSOR. The compress or was a replacement for MFG. P/N 5304478809. The compressor was not an exact replacement. There was no port identification so the connections took a lot of time searching the net and then only the suction port was noted. I had to operate the compressor to be sure of the discharge port.The start relay on the original had no power plug as the new one did so had to improvise by cutting the wiring and adding 1/8 push on clips and then sliding on to the relay pins. I just happened to have the terminals on hand or a run to the electronics store would have been needed. There should have been an electrical plug for the relay in the kit and a port schematic!!
