Default need to bypass neutral safety switch - help

i'm trying to start a 2003 truck and i've swapped a LS1/TH400 in to. the harness is a 03-05 harness. I need to bypass the neutral safety switch to start the vehicle for the customer who may be selling the whole project before i finish it. What wire(s) do i need to jump/power/ground to make the ECM think it's in park so it will start?

Thanks

The range sensor/gear selector switch plug was cut. These are the wires I have.



These are the remaining sensors I have to work with.




I need to know which wires I can bypass for now, but then run to the NSS on the TCI shifter when I install it.

In the last pic, the purple plug is your vehicle speed sensor and the big round one is the one that controls the trans. You can jump the starter and feed the computer 12v to get the engine running.
