4X4 Front Axle not engaging

[Brander]

Front axle will not engage, I can hear the Transfer Case switching when I turn the knob to 4wd but the front axle is not working. Can anyone tell me what wire is what on the 4 wire plug, and what I should be seeing when.or have a pin out so I can jump power to the actuator on the axle to see if that works? Thanks

Is the 4wd service light on or any codes ?

I read this below on another forum
The DB/RD will always have B+. The BK will always be grounded. The other two will have voltage as needed to move the actuator. If I were you, I'd start by checking for codes in the TIPM and FDCM that could be related to your problem because there are several other components that could be preventing 4WD operation.

No engine or 4x4 service lights on, but the cruise control has also stoppped working. I replaced the cruise switch and tipm based off other posts on this forum. However nothing has changed.

Try an find out if you have any stored codes

Might check speed sensor on left front hub , as it could affect the cruise , unsure if it would affect the actuator
