From you distributor pic.
Green (empty) Red
White Black
green (1 degree signal),
black (ground),
red (+12v),
white (120 degree signal).
You need to install a pull up resistor to 12V on the white line.
Also looking at your MSQ, It looks to be set up to run wasted spark. You are running a single coil correct? If so follow below.
"For a distributor based setup with a trigger wheel, simply follow all of the wheel decoder instructions but rather than setting SparkB, C, etc as outputs (as in a wastedspark setup) only set LED17 as SparkA output and ensure all other spark outs are NOT set:"
