68 valiant/ignition switch wiring

J3 and J1 should not result in the starter cranking, and that's assuming your southern cars are wired like "us Yanks."

The start wire is yellow and feeds power to the start relay when the shifter is in park or neutral. If a stick, ignore the latter about the shifter.

"Run" voltage to the ignition is dark blue, but the brown (J3) should be the coil resistor bypass. This gives you a hot spark for start

So what should happen is that you clip the brown to the red, THEN hookup yellow into the mix and the engine should crank and fire.

Drop off the yellow, and it should run with brown connected, but you should not run it long that way, as there is no coil resistor in circuit.

The switch would normally drop off the brown and connect the blue, which then supplies ignition power through the coil resistor.

I have no idea if you guy's cars are wired the same.
