    nope, my car doesn't have the handle. It is a euro
    the car I saw with that extra relay is also a euro , without the handle

    Then it will be a spare relay :)

    do you happen to have the pinout for the 430's e-diff ecu? I've heard for the manual conversion, we need to splice something to power the e-diff pump.

    Here's the wiring diagram, but I don't know how useful it will be

    I don't see a pump anywhere. I have no idea how the system works. If there's pump control, then maybe it's handled by another computer (which talks to the eDiff ECU on a CAN Bus.

    I see some kind of solenoid valve L330. Does that control the flow of hydraulic fluid?

    I think this stuff is best left to the experts like Scud-Ing ;)

    Oh! the pump is actually the F1 pump. I've read that one of the lines of the e-diff pinout powers the F1 pump. When people are doing the six spead converzion, they'll need to splice a wire so that the f1 pump still works and it works as an e-diff pressure pump.

    yep, that solenoid controls a hydraulic cylinder to push the differential discs or release them, much like a clutch.
    That hyadraulic pressure came from the F1 pump, which is shared by the F1 gear shift hyadraulics.

    Doesn't the F1 TCU simply control the running times (duty cycle) of the pump in response to measured system pressures? Wouldn't you have to simulate this function? Maybe the e-Diff ECU has no control at all over the F1 pump.

    You can't run the pump continuously, so, with a manual conversion, you would have to simulate the logic circuits in the F1 TCU for pressure control.

    Anyway, this is "topic creep". Let's stick to the subject of fans in this thread.

    Thermostat test result
    at 100 degree Celcius, the thermostat only opens 3 mm, which is way less than what the FSM suggests.

    Another stuck closed thermostat I have from a previous 360:
    at 100 degree Celcius, the thermostat only opens 2 mm

    I wonder what machnism is the failure? Does the wax inside of the cylinder just leak out during its long service time?

    yes, the original H is 24 mm for both thermostats that I measured.
    in boiling water, the H becomes 24+3 mm and 24+2mm
