Project-Zero: Oil Pressure Switch Problems

I have learned through trial and error that the oil pressure switch use in the Ford Fusion that my engine came from is not compatible with the way that the GBS us wired up.

UPDATE: I chose Solution 1 however that introduced another issue that required me to swap out the switch connector housing. Making a long story short, you want a WVE Vehicle Electronics 1P1883 connector pig-tail kit. De-pin/swap connectors or cut and splice, whichever method floats your boat. (I de-pinned 'cause that's how I roll.)

The Problem

The Ford switch from the fusion is wired to be normally open, meaning that when it sees no oil pressure the switch is open and the GBS Zero's indicator light will be off. When there is oil pressure the switch will close and illuminate the warning light. Neither of the conditions is desirable.

The Solution

Find an oil pressure switch thats normally closed. I present three options here.

1. Standard Motor Products PS299 - Inexpensive, should fit in the ATR oil filter housing without needing to us any adapters, appears to have the same dimensions as the Ford Fusion's pressure sensor, just NC instead of NO. Yay!
2. MOTORCRAFT SW5029 - Inexpensive, used in millions of Ford cars. Should fit in the ATR oil filter housing.
3. ACDelco 8020 - Opens at 5psi, inexpensive, used on millions of cars since the 1960's. Doesn't fit in the ATR oil filter housing because hexagonal body is just a bit too large. You would need to mount this in a remote location.
