electrical issues with the 67 fish

I have a 69 4spd in my 67 and there is no neutral safty switch, just back up light switch. I`m no autoelectric mechanic, but concerning the ign. switch, you know the run circut is good, just not the start circut. It seems you could use a test light to determine which terminal on switch is start circut and if you turn key and it does`nt light, trace wires from there. possibly a faulty switch if wireing checks ok. BTW redfish will be the "man" to whoop on your gremlin8)
