You will definitely need the resistor but the diode would prevent any feedback of current to the ignition system. In most cases it isn't needed because the resistor drops the current enough in the reverse direction to prevent the feedback. I wouldn't install it unless you get engine run on.
The brown wire will go to the L terminal and the S wire (voltage sensing) will go to the S terminal. Run it to the main junction of the alternator and battery.
If you have the battery charging gauge and you want it to work you'll have to run the alternator charging output wire to the main junction. Some guys run it to the battery positive terminal directly and then can't figure out why their gauge don't work.
I think I've posted this diagram before but Here it is.
