Re: No 4X4 lights...
Red is not a power feed to tccm.
ATC fuse powers the orange wire to TCCM.
The 4WD fuse powers the push button switch on brown wire.
Make sure both have power key on.
And alsp power on the switch and TCCM terminal that the wires go to plus check for good ground.
If plug in or wire wiggle makes thing come and go you have a problem there.
Also some switches have bad solder joints.
