I spliced the ground black wire from harness and it worked for a minute I could hear the actuator working then it failed and the 4 wheel light came back on

Here's the thread I made. Post #11 has the parts I was talking about and how I tested mine. Maybe that's your problem?

I hope this helps: https://www.performancetrucks.net/fo...essage-560255/

The black wire goes to ground on actuator harness

RB04Av

The black wire goes to pin A of the control module, labelled "CW" on the schematic. It only gets grounded when the control module grounds it. Which is, when it is commanding the motor to spin in one direction. It ends up going to battery when the module is commanding the motor to spin the other direction, at which time the red wire, which goes to pin B of the module labelled "CCW", gets grounded.

Which is probably why the motor now goes all the way one way and can't come back the other way... the module can no longer reverse the voltage on those wires like it's supposed to.

Pin C of the module goes to ground. Pin D gets 12V from the ATC fuse.

The black wire DOES NOT belong going straight to ground.

​​get off my thread I don't need your extra stuff

What did you see when YOU looked at your copy of the schematic?

If you're not interested in how the thing is actually wired, you'll NEVER get it to work.

Replaced transfer case encoder now in stuck in neutral and 4 wheel light came back
