Your right most relay is just activating the center relay. I guess I shouldn't say its not being used, but its not serving a purpose. Like I was saying, you never want to have the high draw side combine with the low draw side. In this case it wouldn't hurt anything, but it just doesn't really make sense to do it that way.
Let's trace the current:
Let's start with the toggle switch. There is a circut between the toggle switch and the right most relay, the low draw side. We'll call that circut #1. When you flip your toggle switch, it activates the right most relay. A relay is nothing more than a switch itself, so activating a relay means it closes another circut. This is the high draw circut. This will be circut #2. This circut right now is going from the high draw side of the right most relay, to the low draw "switch" side of the center relay. In other words, when you flip the toggle switch, it closes circut #1, which in turn closes circut #2, which activates the center relay and closes the circut between the relay and the high beams. Having said that, you could do away with the right most relay, hook the toggle switch to the center relay, and the system would work exactly the same.
Now the problem is, and this is why you need 2 relays, you have a wire going from the 30 terminal to both the high beams and low beams. This will work on the high beam setting, as both bulbs will be on then. But when you set it for low beams, power will go to your low beam bulb, and then trace its way back up the wire to the 30 terminal on the center relay, which doesn't matter because thats an open circut, but on that same terminal is the wire for your high beams. This creates another closed circut to the high beams, and will end up turning both bulbs on again. For the sake of keeping things simple, just follow one rule of thumb here, this will help a little, don't hook more than one wire to any terminal on anything in the high draw side of this set up. Any time you hook two wires to one terminal, you also create a connection between those two wires, even if the switch for that terminal is off.
You're close though, so we can fix this real easy. Take the jumper thats going from the left terminal on the right relay to the bottom terminal on the center relay. Hook that wire to the bottom terminal on both relays. The toggle switch wire stays where it is, but is now connected to that wire you moved. Now take the wire going to your high beams off of the left terminal on the center relay. Move it to the left terminal on the right most relay, the terminal that you just pulled the other wire off of. Do those two things and you should be ready for blast off.
