All the locations the backup light signal shows up

Ok, so my back-up lights don't come on.  I figured the connection was in that black connector that comes out of the trans hump and goes into the dash, but I have this connected and they don't work.  Should this signal show up on the column?  I don't know why it would (maybe for auto cars, same wiring?) but that's the only place I modified the dash harness for the SN dash (so far).  where do I find it?  What am I missing?

Dang, ok for one thing I'm stupid cause I forgot I HAVE an evtm.  Next, why do I have no back up lights?

I did 'eliminate' the system sentry unit.  Could this be the problem?  I also have no working gauges in and I don't believe I made any connections for this at the column (multifunc/ign sw).  Am I overlooking something obvious?  Everything else seems to work...
