Does the dark green wire coming out of the neutral safety switch had power when in the crank mode?

Okay, correction, the red wire going into the ignition switch has 13v.
The yellow only has 5 but the red w white stripe has 13v.
Now I'm going to check the green at the NSS.

Are you still with me Ken? I ran a separate wire strait from the battery to the dark green wire at the NSS connector and all sorts of things come of. All the gauges started working properly, the security light went off and u could feel the gear shifter sort of tighten up. But still no crank and no PRNDL indicator.
