3 & 5 could be reversed and the relay will still operate. With key on you will see battery on both with one lead to ground. You will be reading the voltage through the winding. You need to lift the wires off the posts to isolate them and then read their potential with key on.


Edit: Nice diagram Jim. Does what I said make since?
