My truck has sat for years. It will not crank. It will crank if I jump to the signal wire of the solenoid. I have no current from the S wire. The ignition switch was replaced because the detent felt bad. There are two large gauge yellow wires that look like feeds to the ignition however only one has current. I have a horrible Haynes manual that does not show complete wiring diagrams. Does anyone have a diagram of the ignition switch wiring ?
Thanks

Here's a diagram. It's not the greatest, but it does show how the power enters the ignition switch, then the red/blue to the neutral safety or the clutch interlock, and then to the s terminal on the starter relay.
