tranny help

[rickfabio]

Hey there guys, well, from my other thread: https://forum.ih8mud.com/70-series-tech/221552-t-case-help.html
i think it's safe to say i have a ln130 diesel tranny and t-case setup with the electric shift setup, as seen on this dude's thread: https://forum.ih8mud.com/79-95-toyota-truck-tech/157712-91-pickup-diesel-conversion.html

my question is, does anyone have a wiring diagram for the 4wd system? seeing as it's in a jeep kit car with no a.d.d and manual hubs i figure it's just about hooking up an indication light and switch to activate, but i have no idea where to start with the wiring. It all comes from the tranny to engine bay to 2 plugs that are blanked off.
Any assistance would be appreciated
Thanks
Rick

I would think there would be a ground, then three wires min to engage 2hi, 4hi and 4low.

B+ would come from the instrument panel I suppose in a stock truck.

Anyway, that tranny is pretty common in the diesel Surf from what I quicky read. Use that link and see where it takes you in terms of information.

I am sure those fellows will have a wiring diagram for the truck/chassis/driveline.
