Determined correct connections
I wired together a test hookup using my trickle charger to power the fuel pressure controller (FPC) and my battery charger to power the fuel pump via the removed fuel pump relay contacts. I confirmed the following connections for the fuel pressure/temperature sensor:
Pin Signal
1 Pressure output
2 +5 vdc input power
3 Temp output
4 Ground
I powered the pump long enough to fully pressurize the fuel rails and then let it bleed down. I used the Banshee M90 kit supplied fuel pressure gauge and my voltmeter to get data points to compare to the FPC provided table:
0.50 volts – 0 PSI
1.2 volts – 10 PSI
1.65 volts – 20 PSI
2.2 volts – 30 PSI
2.75 volts – 40 PSI
2.89 volts - 43.5 PSI
3.45 volts – 50 PSI
3.9 volts – 60 PSI
4.6 volts – 70 PSI
Identified by black "x" below
My data points identified by red dots above
0.45 volts - 0 psi
1.93 volts - 25 psi
2.30 volts - 40 psi
3.12 volts - 50 psi
4.28 volts - 67 psi
I removed the instrument cluster to install a boost gauge and oil pressure gauge. I now have access to a wiring bundle that probably contains the pink/black wire from the inertia switch shutoff.
I may decide to interrupt it behind the instrument cluster.
