Well so far I haven’t found the part number for the Trooper TOD ECU. This is a layout of the two different TOD systems. It looks like even with the clutch pack disengaged there will still be a minuscule amount of friction in the clutch pack. So there will always be a little power going to the front. My plan is to have the TOD go into 2H in the way it was designed to go into 2H and not try and trick it. If the ECUs match and I figure out WTH the axel position swtch is for. I’ll start doing some test.

P.S. Some info on the JDM TOD would be extremely helpful.
