engine wiring help

ok so i think im getting this. connect the brown and blue together and run it from bulkhead and run it to the +coil? or to the dist? now for the alt the regulator wire and the other wire besides the hot needs to be connected together??? or all 3? thanks for the help and a big thanks for the diagrams...although i cant read em to good haha... and lastly since i do have a 4 wire ballast (which i forgot) what do i do with the other 2 wires? i wish you could just explain this to my harness guy because im obviously a newb to wiring... haha



and another last, last thing. my alternator is a 200amp for the stereo ill be running. im thinking i should go bigger wire for the alt for that reason

once again thanks
