Hy PatinaFiend, hook the positive battery terminal to the starter power in post, negative terminal to a good clean ground (a starter mounting bolt is an excellent choice). From the starter power input run a 14ga. or larger wire to the power terminal of the ignition switch. From the ignition switch ignition terminal (some switches have an "ign1" and an "ign2" terminal) I believe the one we want for your setup is "ign2", run a 16ga wire to the top terminal of a ballast resistor on the firewall. From the bottom terminal of the ballast resistor run a 16ga wire to the coil positive terminal. From the power terminal of the ignition switch run a 14ga wire to one side of the push button switch on the dash, from the other side of the push button switch run a 14ga wire down to the starter solenoid terminal closest to the engine block. From the other small solenoid terminal run a 16ga wire to the bottom terminal (to coil terminal) of the ballast resistor. If I haven't forgoten anything that should allow you to start, run, and shutoff the engine from inside the cab, if it's easier you can use all 14ga wire (bigger is better), hope that helps.
