is this a "simple" fuse circuit, meaning that there are two wires that lead to/from the fuse in question, or is this more complicated where the fuse is just part of the TIPM and is allowing communication between two points when the fuse is in tact? if it is the first scenario, one could expand on this mod and find that wire in the wiring harness and run a simple wire with a switch to it inside the cabin and create 4WD on demand. consequences of flipping the switch while the car is running would be at the risk of the user, however.

EDIT: i totally didn't see post # 3 lol. but the switch wouldn't work if the fuse is just allowing communication between two contacts within the self-contained contained TIPM.

@IRSmart : I also have a gut feeling there is more to this fuse scenario... Doing AWD On/Off like this would be fabulous, but there very well could be strings attached... and problems looming...

I couldn't agree more. I am happy to be a spectator in this exploration.

I think I have an idea................I'm not electrically inclined at all. But would something like this work.

Add something along those lines and wire a switch in, or just go the safe route and pop the hood and put the fuse back in...


Other thing I just thought of. The owners manual states that power should be shut down to the circuits in question when replacing the fuse, so on the fly switching might cause damage.

No, that's a tapafuse meant to grab power from a circuit board without interfering with what it's plugged into. The idea would be to do the exact opposite.
