Below is the Accel coil mentioned above mounted on my 98 ST350. It has a Red MSD base that solves the primary wiring attachment problem on the bottom of the coil.
I'm still having trouble getting the 4 wire HEI Ignition module to work though. It will run but only at high RPMs and rough at that. I have tried swapping the pulser coil wires and took the module to Autozone to confirm its good.
Any ideas on this would be appreciated. I may redraw the diagram above for a 4 Stroke to make sure I'm not missing something.
