one more electrical problem

[b5blueaar]

Connected to one tab of the starter relay is a yellow wire from the connector on the firewall. Connected to the other tab is a large brown wire with yellow trace that comes from the nuetral safety switch on the transmission.
When key is turned to start, the relay will not pull in. When I check voltages, both wires have 12 volts.
I can remove the brown wire and connect a ground wire to this tab and everything works fine.
Is the brown wire from nuetral safety switch a ground?
Why does it have 12 volts?
How does the nuetral saftey switch work? It has 3 wires connected to it.
thanks for any tips.

the 2 outer prongs on the Neutral saftety switch operate the reverse lights , power in & power out to the lights , the center prong is the ground for the start relay ,  you neeed to find out why you have 12v on the center wire

My guess would be a short to power somewhere... follow the wire... that's the best advice I can give...
