To figure out how to get that signal from your switch, I would use a tester to determine which pin will give you the signal you need.

I'm assuming you have a Gen III since you have a 4L60E, if so you should be able to connect the white to your TCC wire and be done.
Thanks, it is a Gen III DBW. I will be attaching the TCC wire to it but I am using the factory switch down on the trans as my NSS, because I have an aftermarket column shift that does not have a provision for the NSS.

Thanks!
