Ok fellas I am going to make this a sticky so that everyone can always find it if they need it. I am starting to get into the wiring part of my engine swap and I decided its time to go ahead and rewire my headlights with newer relays on a designated circuit separate from the dash or engine harnesses. This is really simple and I will add to it as I complete the project. For starters I wanted to throw up this Awesome diagram that I found for wiring a headlight relay circuit.

I did this modification the day I did my hid conversion.  I tested it on my oem headlights before I removed them and I will have to say that there was definitely a big improvement over the stock circuitry. This modification allows current to come directly from the battery and charging system. The oem  design has the power running through the dash harness, through the switch and back out to the lights. The voltage drop through all of this wire is considerable. Another benefit of doing this modification is that it reduces the load through the factory fuse able link, and all of the wiring in the dash harness.  This modification costs 15$ or less using 2 relays and some short lengths of wire and some connections. I highly recommend this for factory trucks and it is a must when running aftermarket lights such as HID's.
