Thanks Truckrolet. According to the wiring diagram in the shop manual, there are two 20 gage green wires coming from the same terminal on the ignition switch. One goes to the coil and the other to a resistor mounted on the firewall in the engine compartment (from what I can tell from the diagram). I disconnected the wire from the resistor, and I cut the two green wires at the ignition switch and tied them together to a 10 gage wire run separately now to the coil (well, and I also later installed a relay to get power straight from the battery, fused, with the 10 ga wire just sending the signal to the relay - exact same results either way).
