Does The Definitive Tod Off Switch Thread Exist?????

[pbkid]

...Thinking about it more, maybe you can get around the resistors if unplugging the ECU doesn't cause a check light. I wonder if putting a switch on the ECU 12V wire would be the same as unplugging the ECU? Then you wouldn't need the resistors or relay and it would be a really simple modification.

ya, i dont think you would need resistors if you just cut power to the ECU instead of cutting off the clutch/solenoid.

judging by the write up that you guys are referring to... the person who wrote the thread actually put a switch in line with the front speed sensor, not the solenoid clutch.
I've done some research on this at work (for a fellow VX'er), as I have access to factory wiring diagrams from Isuzu, and the solenoid should actually be a yellow wire.

VX where did you add the relay for the factory switch in the wiring?

The relay replaces the aftermarket switch shown in the write up & the OEM 4WD switch is installed on the 12V power for the relay. When the relay is energized it connects the ECU to the resistors & de-energized it connects the ECU to the clutch.

You would think a simple power on/off would work, but it might trip that insanely annoying check light... I just don't know.
