So to sum up, when the wires appear correct on both:
OE- zero with key on, pegged above 5 when running
FAE- slightly above zero with key on, pegged above 5 with autocheck warning

Ah jeez. I have a confusing update.
OE- zero with key on, pegged above 5 when running but now very randomly sounds the oil buzzer.
FAE- now AT zero with key on, stays at zero while running regardless of load or rpm lol

How TF do I keep buying new defective items!? The FAE oil pressure sender was also defective. OEM VDO sender worked as soon as I installed it.

Pretty strange, looks like you have a bad FAE sender and possibly also a dodgy connection in the loom somewhere. Have you checked the crimps at the sender end for tightness and or corrosion? Don't know if you're on original loom or custom. I would be tempted to cut the old 1/4" Amp connectors off and crimp on new ones. You need the correct crimps and tool though, the things with the coloured plastic sleeves are hopeless

No worries. It works great again on original loom

Engine runs quite healthy at 30 psi on the holsets. No oil in catch can
