317 compressor wiring

[LAY N LO]

The relay I have for my ART 4000 system has 5 wires coming out of it. The red and black are marked battery, the white goes to the pressure switch, but I have no idea where the blue and green go. Any help would be greatly appreciated.

wire harness the blue and green go to the compressors.If you only run 1 compressor then use just one wire...White pressure switch,red/black positive...
