Hey wondering if anyone could help me out got a new sanden 508 for an original ac truck and need to wire it. A black and a dark green wire go into the og compressor. The sanden only has one black wire. I’m assuming that because the dark green is switched 12v from the poa valve/pressure switch that, that dark green wire should go directly to the black wire on the sanden? Is that the case? Have any of y’all done it? Is there another way I should be wiring it? Anything helps thanks!
