Now I pondered the situation of how i could easily improve the diagram. The short answer, ground the yellow wire to the low beam. The only problem is if you are running bulbs that are rated higher than factory, then this will cause a short. The factory wiring is 18 awg which is rated 7-10 amps. With the stock bulbs you will be running 9.4A. This is not taken into consideration a spike in the current under load. ( best to measure at the bulb with a multimeter) Secondly, there isn't anything protecting the bulb from shorting if there is a surge from ground. (Say lightning)
Therefore, the cheapest method to improvise the circuit is to use a diode connecting low ground to high ground after the bulb ( direction to High) However, you must use a diode that is rated for the amperage. (radio shack aint gonna cut it) Unfortunately, now the diode is a point of failure in the circuit.
So how do you fix the problem? Well, I found a solution which i will explain in a tutorial posted on youtube. The link will be provided below.
