Front diff. actuator 96, Sierra

I have upgraded to the new motorized actuator but i can't seem to find the brown wire on the four wire connector on the tranny. Hopefully someone can help.

im having same prob, please help if u find a way

You should be looking for a connector on the transfer case, usually on the drivers side just above the driveshaft to the front axle

brown to blue is what my dealer told me.stil have problem . engages but wont dis engage
