no fire,a bit lost....

So everyone I still havent put a meter on anything yet.As soon as I can get one its next in my troubleshooting.What Im trying to rule out is the neutral saftey switch.My delima with this is my trans is a 86 727 with the nss on it.My duster was originally a 225 but iv'e not seen a harness for a nss.Whats up with that.Is this something I need to keep diggin into?
