HEI in Mopar ECU casing

The second pic is not the one I did.
I just used that pic for the wire connection points.
Whoever did that one sucks at soldering.:D

Hey Trailbeast this is what I have so far. All 4 prongs on the GM HEI module have a letter (might have to blow up the pic to see). I want to make sure I wire this correctly. This is what it looks like I need to do. Correct me if I am wrong. So B goes to 3. C goes to 4. W (the big pin) goes to 1. G goes to 2.

Also, I hollowed out the BACK of my ballast resistor. I plan to run a wire between the two prongs in addition to what is there, essentially eliminating it. So my factory wiring will still plug in on the front, it'll look stock, but won't be functioning. Is this ok? Am I understanding this correctly?

So I can use that heat compound on the side between the HEI and the ignition box and that is enough heat sink? Stuff like this? Super Lube 3 oz. Tube Heat Sink Compound-98003 - The Home Depot
Do I need to ground it, if so, where/how? And do I have to make a bracket to go under this thing or can I bolt it back onto the apron? Can I leave the HEI "floating" only attached by the soldered wires, or do I need to actually mount it in the box? Thanks for the help you guys.
