Just take your time. one thing at a time, think of the electricity of a flow of water. Goes from the battery to the ...(whatever device your worried about) and if it can't get past this item, what is it? a relay will only work if the right conditions are present, a diode will only let electricity go one way. Power hits the switch, and you pull the switch it works or doesnt.
I have to wait for $$ for me to make this mod. but its on my want list.
