purple ignition wire

[az1970k5]

I know this is a simple fix but I hit a mental block. The purple ignition wire on my truck is cut and jumped to another purple wire that goes out the firewall. Is this for the neutral safety switch? If so can anybody be so kind as to point me in the right direction to get this hooked up the correct way? I know my safety switch has one connector with a green wire and a light green wire. The blazer also starts in any gear
