Neutral Safety Switch Wire?

[Rdobbs1977]

We're working more on the drag car today and I'm puzzled as to a particular wire and hope someone could tell me what it does. Here's how it goes:

From what i can see: Previous owner had 2 wires running from push button starter. Of those 2, one goes to fuse box, and the other goes to neutral safety switch at the shifter. Also, An Orange wire is spliced/mated into this one NSS wire that goes into neutral safety switch spade. From the other spade on the neutral safety switch, a wire is ran back out from the NSS and into the engine compartment. This wire still has the markings 'safety switch,' so we know it goes to starter and is in general location where it should be in the engine bay. What I cannot figure out is that orange wire i mentioned earlier. It too shoots out into the engine compartment but have no clue what its there for? does it too go to starter? I dont know but would like some thoughts
