To answer your ignition switch query, I am now using an aftermarket switch that has 4 posts on it. A triangular configuration with the 4th post in the middle.

As per the instructions, the ignition position (lower left of the triangle) labled "ign" goes to switched ignition power on the fuse block out to the firewall, and the other goes to the coil.
The top position, labled, "bat" goes through the fuse panel into the firewall and connects to the left side of the solenoid along with the hot from the battery and a lead to the alternator. It is shown in the picture with 2 wires being spliced and the output to the solenoid
The lower right side of the ignition switch, labeled "acc" goes to the fuse block "acc" input
The middle post from the switch, labeled "st" is routed through the fuse block and is the red wire hooked to the right hand smaller terminal in the picture along with a black wire that goes to the + input of the coil

OK everyone, I fixed it! Turns I had a wire running from the other small terminal to the coil along with the hot wire from the ignition....can't remember why. I removed it and Viola! I starts great.

Thanks for all the worthy suggestions. I look forward to future engagements on this forum!

I think what it could be used for (assuming you were using a Ford stock solenoid relay ) was a coil ballast resistor by-pass, so if you had a points style system, with a ballast resistor, it would supply full available battery voltage to the coil while the engine is cranking, helping the engine fire off better when it is cold. If you are using an after market electronic ignition, most of the time that feature is not used. If you were using a Ford, stock solenoid relay, (looking at Ross's diagram and soleniod picture) you would connect that wire to the "I" terminal on the relay and the other end would join your IGN wire on your coil. Since you are using an aftermarket relay you could simply connect it to the starter cable terminal (your right hand terminal) and run the other end to the coil terminal. But this is only if you are running a ballast resistor. If you aren't, there is no point to doing it in my opinion.
