Default MS1v3.0 launch control inop

my MS1v3.0 has been sitting in a box almost 18 months before it made it into my current car. launch control worked on my last car just fine but i cant seem to get this figured out.

i double checked my launch control settings and everything looks like its correct. i double checked tps calibration settings also. i have .1 ohms resistance to ground from pin 6 of the DB37(wired JS11 to SPR4) with the clutch engaged.

im lost. anyone have any ideas?

First, check the voltage. Do you have 5 volts on the launch control input with the key on and engine off, and have it drop to zero when you put the clutch in?
