Cleaning up harness. Neutral Safety Switch Help.
 

I will preface this with:
Donor: 2004 6.0/4L80E out of a 2500 Suburban
Recipient: 1969 Checy Suburban (396/TH400)

I spent the day following LT1Swaps instructions and videos and modifying the stock LS harness. When I was all done cleaning it up I had 2 mystery wires left towads the end of the harness by the fuse block, a dark green wire and a gray wire. I believe they were from either the C150 or C151 connector I cut off. I rang the mystery wires out and found that they went to the neutral saftey switch connector. I am not sure what they do and what I should do with them? In the picture the one marked GR is where the gray wire rang out, and G is where the green rang out.

Can someone give me some guidance on this? Appreciate it.



Also, if I wanted to run the 4L80's NSS inplace of the original NSS on the column of the 69 suburban how hard would that be to do and how would I do it?

This should help. It will also let you use it vs the one on the steering column. I did mine this way and it is much more reliable than the column.
