transfercase diagram

[iam_canadian22]

can anyone get there hands on a wiring diagram for our crappy BorgWarner 44-44 transfer case? would like to see if there a way we can apply an external power source to keep it locked in 4wd when we select 4lock and 4low, that's if it indeed uses electrical signal to engage

Ive got no access to a garage or hoist probably until summer, if any one wants to help to try to figure out which wire engages the 4wd clutch when the rear spins, once i find that out ill do the testing of applying full time switched power to it

I looked at that diagram and I don't see anything that goes to the clutch pack. But I'll be the first to admit that wiring diagrams aren't my strength.

My folks have a garage so I'll see if I can get over there and take a look at the wiring. I would love to have a switch that locks it up until you turn it off. This tcase would be decent if it just engaged the clutch the whole time its in 4lock/low. Breaking it free once its locked will take quite a bit of torque.

I'm really hoping its not a mechanically locking clutch, like through centrifical force or something. That would pretty much seal the deal on any hope of these tcases being decent...

No, it is a wet clutch, just like in a transmission.

The wire that controls the clutch is tan in colour. It's pretty obvious which one it is, it's the only wire that doesnt go from the connector to the shift motor. It goes from the connector to rear housing.

As for adding an external control, it should work however it's very likely going to set a dtc and disable the system. The DTCM( Drivetrain Control Module ) monitors the clutch control circuit and if it detects voltage when there shouldn't be it will set a dtc and you will get a Service 4WD light.
