Start again:
DR= DR0
White wire to test mode
Black wire to ground
or
DR = DRO
Black wire to test mode
White wire to ground
The HFS6 does not have an orange wire.

Thank you Richard,
What is DR=DRO ? I am confused with that line.
The orange wire is not on the HFS-6 but rather is the wire on the Subaru ECU that is used to ground the green test mode connection signal the ECU receives when you plug the green test mode connectors together.
My observations indicate that when the white wire is grounded, and the system is NOT energized (power off or switch on the gauge is off) the black wire is also grounded. It is only when the system is energized and the switch on the gauge is depressed that the circuit switches open. This is a problem when first starting the car. It triggers a CEL when starting the car some times.
What I really need for this to be perfectly effective, is a circuit that is OPEN at all times UNLESS the fail safe is TRIGGERED. The only time that circuit should be closed (grounded) is when the system triggers fail safe, or the HFS-6 is switched off at the gauge.
