No start, wire on coil

To jump in for a sec - yeh I made a pun. I just finished up this 70' and had the ENTIRE front end harness out of the car during restoration. I've been a GM guy for a long time / but always wanted to own one of these. So to the point lol. I inspected and made repairs to sketchy looking stuff and retaped. Everything back in and ready for first start..nothing..battery up and fed by charger. The car had / still has the common Mopar Orange box ecm and an upgraded electronic pick up distributer (No Points) and a ballast resister. We replaced both batt cable ends at batt / made sure the block was grounded at firewall / neg cable contacting bare iron on block front and rear and grounded neg cable to scraped to bare metal radiator support connection. I should mention we " gutted the column shift parts from the column " replaced the main ignition switch/harness and installed a floor shifter. We now had an engine that turned over but would not fire. We found that the ballast resister was not getting keyed on power to one side / we traced and found a wire to splice in. We ALSO discovered that this particular build did not like having the " 3 pin " transmission plug ( neutral/reverse ) plugged in and by accident with the key in ON position with the trans plug on it would turn over the engine if it the floor shifter was shifted...yikes!!!. So...with the wires correctly on the coil ( no condenser ) as stated above in another reply and the ballast resister happy it began to fire !. We played hell getting the distributer set in correctly to allow the base to be rotated without the vac can running into the intake. Happy to report it starts right up now..but have found thats not always a safe bet & I think its because of the new ( colored ) battery cable ends not completly "worn in" and I keep a 1/2" wrench and a flat blade screwdriver with me at all times. And yes that trans plug is staying unplugged for now. I just make sure its in park before I twist the key.
