The triangle is independent in function with the diff itself, IOW if you push
the switch the triangle should come on with ignition on.  The graphic doesn't
light until the actual diff is engaged.  If neither is happening, you don't
have power to the switch and/or the controller.  Use a test light, and go
under the rear seat and ck the connector at the vaccuum box, the blue/red
should be the feed for power, I believe the black/blue is connector power,
all browns (solid or with stripe) are ground.  Next ck for power at the
switch connector, it's also the blue red.  The diff lock light itself is a
ground circuit, which means that the power going into the switch assembly is
on when the ignition is on and the diff is locked.  It's definitely a power
problem, not a ground problem.

Sounds like a sensor out of whack.  Usually it's the fronts.  Pull both
wheels off, ck the sensors, they should be close to identical in placement,
orientation and depth.  You can adjust them in or out.  Normally, when the
abs is kicking on as you describe, one of your sensors is too closee to the
driveshaft spline.
