This option is for HFS4 only.

1. You can connect the Black wire to the blue wire of the green harness.
2. Upon the EGT voltage exceeds the AUXFX trimmer setting, it can either turn on the Water tank level led (W) or trip the failsafe to drop boost (F). You can do both at the same time if you solder link them.

Can you post the Voltage vs EGT Temperature chart here?

Where exactly is it?
In your circuit in the picture does not have a blue wire.
Draw a diagram.

In any case, connect the jumper, I disable the boost controller.
I understand you correctly?

there are 6 wires in the green harness: Not shown on the drawing.

1. red ............. DI (+)
2. green .......... DI (-)
3. blue ............ Aux Failsafe
4. Yellow ......... Flow sensor signal (analogue)
5. White .......... Flow sensor raw pulses
6. Black .......... Signal ground

Here is a diagram:







EGT ........... 800C = ~2.6V (just above mid point on the AUXFS trimmer.

Do you mean they are reliable?

Do you have a HFS3 or HFS4?

yellow4 and white5 wires are in communication with
#5 ........... System start-up: 12V = system on.
#6 ........... Flow sensor signal: 0.5 to 4.5V
#7 ........... Water level sensor: 0v= empty, 5v= not empty
#8 ........... Fuel injector (-). not direct injection.
#16 ......... IDC% signal: 0 to 5V
#17 ......... MPS signal: 0 to 5V (signal conditioned)
#18 ......... IDC% to the water injection valve
#23 ......... System power: 12V (switched/fused)

The white wire of the green harness is not amongst the test points.

On the last page but one of the user manual, all pin out from the controller is described.
