Still having an issue...UPDATE...

Jay anything that increases the current draw through the TFI module will increase heat. Example Plug gaps coil types wire types there resistance and even the resistance of the plugs that are used. That is why i only use stock components that reduce the heat in the TFI module. If you have a chance set up a dummy ignition system in your shop and read primary current with different components gaps and types of plugs ETC. You will be shocked at the difference, The TAURUS also used a remote TFI . I tried using a split TFI module for mounting the 3 leads needed for the remote but could not separate it successfully. So i just use spade tips with a dab of solder and use the mounting holes for the TFI to make a bracket for strain relief. A simple cable clamp works great ans a bead of silicone to seal the wires nicely in the dizzy.

yeah, i get what you are saying, that method makes sense, de-complicates is drastically.

I dont have the kind of tools to see that much ignition system deviation like you do, and i would like to see this in action one day, would be interesting to see the extra load exerted on the tfi due to after market spark components.

So we are still focused on heat,, thats the good part to know, remote mounting and heat dispation coupled with location of the coolest spot is still priority 1. Those with add on higher impedence sub systems or parts are just gonna have to manage the risk,, thats all,, in the end its a good mod for just about anyone who has basic wiring skills.

Here is the diagram for the ignition circuit on the 87-93 Mustangs:
