So i need abit of help getting the Ac to work in my s13,
Its a 1992 factory digital climate control and i've relocated the engine bay fuse box to behind the glove box.
I've also removed the standard ecu and any other unnecessary wires.
The car has no motor or compressor in it at the moment so no refrigerant in the system.
The only way i can get the AC relay to engage is if i earth the green/yellow wire that used to go to the standard ecu but
weather i press the AC button on DCC unit or not the relay is still engaged.
So does anyone have a wiring diagram that could assist me?
Picture of my car for attention
