Check the fuse 
You guys need to tremember that all this NSS switch does is allows power to run through it depending on what position it is in.
That's all it does.
It closes the circuit.
In Park and neutral... it allows the start circuit to be closed
In Reverse.... it allows power to run to the back for the BU lights
To bypass switch ....You have to get power to the LIGHT side of the switch to test for illumination.

remember guys when you put the neutral safty switch on you have to have the transmission in neutral and use a #43 drill bit to line up the switch then tighten down the bolts and take the bit out.

The NSS pictured in post #24 is for 1967/77 F100/350's = steering column mounted. (C7TZ-7A247-A ~ Motorcraft SW-600)

Bill , I referenced the Pre 78 NSS because of what he said in post #11.
I interpreted it like he had a substitued NSS by a P/O.
His 79 color coded wiring is wrong by his comments.
Pehaps a later year harness on it ?

I looked on the back of the fuse panel....no white/pink wire.....
there is a white/ purple.....
nothing is cut or looks like its missing.....
Is there another place that the wire should/could be hooked up for the 12V even though all ford diagrams show nothing from fuse panel to NSS for the white/pink wire...
