    I have a dauntless 225 , the po did some crazy thing to the wiring. I have run a new wire from the ignition switch to the resistor. looking at drawings it shows a 2nd wire coming into the ignition circuit. My starter has 3 connection points. Large terminal for battery to starter, A s terminal and a r terminal. s goes to the s term on ignition switch. Where does the "R" terminal go. he had it run to the accessory term on the ignition switch which does not appear to be correct.
    As I now have the resistor and the coil wired, my wire from the ignitron switch, ignition terminal goes to on side of the resistor , power would go thru resistor to the coil.

    Just ordered parts to rewire lighting so I have my work cut out for me. need to get new engine started then lights. help please

    looking at FSM wiring for the V6 . doesn't show a wire from starter to coil . my 71 doesn't have one either
    there has been talk about adding a wire from starter solenoid R terminal to the coil side of ballast resistor . it supposedly adds 12V to coil when in start cranking mode

    That is correct. Jeep didn't use the R term (bypass circuit) that I know of. At least not on any of three rigs I have or had.The concept is fine but not really needed on the dauntless motor. If you have HEI or Petronix you can ditch the resistor too.

    I don't have hei or petronix, this jeep staying bare bone no electronics. I have spares of resistor, voltage reg, want to keep old school. I will use r to coil, saw in painless wiring guide and looked at other sources, just wanted to make sure. The po had a fur ball 1 foot in diameter of wire under the dash , wire cut with butt splices on the end going no where. triyng to cut out the junk one circuit at a time. After get motor started Thursday or Friday. I will start on light , turn signals, back up lights, brake lights. Next week radio, heater, lighter ,the jeep has ash tray wipers so on.

    You just don't see ash tray wipers anymore.

    You will have a 10 gauge Red wire from the Bat term on the alternator going down to the large terminal on the starter solenoid. You will also have a 12 gauge wire from the "R" terminal of the solenoid and running along in the same loom with the RED wire to the alt but will continue on to the + (positive) terminal on the coil. That's the way it should go. Note: The "S" starter wire should be in this same loom. This is providing you have the 225V 6 with the Delco starter in your 57 willys. If you fill out your profile it will be easier for other members to know that you have a frankenjeep.

    Depending on the ignition switch, you *may* not need the R wire to Resistor. On vintage GM cars the ignition switch didn't provide 12v to ignition circuit during cranking. The wire provided a full 12v to ignition during cranking. I don't know about the specifics of your ignition switch but it may not be required. At any rate, it should be on the back side, or coil side of the resistor.

    Not to be pedantic, but my understanding was the resistor and bypass were designed and installed so that the ignition would get it's accustomed voltage when cranking.
    That is to say, the battery voltage would drop to 9-5-10.5V when cranking so if you didn't want a weak spark you had to design the ignition so it ran on that ~10V. Then add a resistor so you don't see a high voltage while running and charging at ~13.7V.

    In any case, my 1967 jeep was far from stock electrically but did have a very factory looking bypass wire from the solenoid to coil.

    my coil is 12 volt I did install the bypass.
