I just finished my relay mod and my pro comp headlamps are now brighter than the 130 watt H3 driving lights. As I began to akin the factory wires, I found them to be 18 ga and replacing with the 12 ga is such a change that it is unbelievable, even reading this thread several times. Thanks again for the write up, and if you are only marginally good at soldering, take your time and it will really pay for your time. Just remember: SOLDER YOUR CONNECTIONS!!!! We are talking headlights here.

I just did this on my brothers ford Taurus it had 9007 bulbs. I ordered new connectors and relays off eBay. I didn't notice any brightness benefits. But he was having issues with blowing bulbs. I'm hoping this fixes it.

I had kept my headlight wiring after the relays. I had installed the relays in my headlight circuit near my bulbs. I had used a 12ga feed to my relays and I had used the stock headlight switch and wiring to activate the relays.

And yes, I had seen a significant difference in my light output.

That's good to know. Maybe you saw a difference because the relays were so close to the headlights and it counter acts voltage drops?

I just installed the relays without upgrading the wiring to see what happens, and I had definite lighting difference in the density of the light on the ground and slightly whiter light. Having that said, I will still upgrade the wires in the future for there is still more to be power to be unleashed thanks for the killer write-up.

Yes, the relays are only about 6-8" away from the left headlight and are only about 3-1/2 feet from the right headlight.

i don't know if it is possible but can anyone dumb down this mod a bit for me? Usually when it comes to auto wiring I am freaking useless. I would really like to do this mod but don't quite understand the diagram.

What is it that you don't understand? It is really straight forward in my book and believe me I am no wiring expert.
If you go back and re-read and look at the wiring drawing I think you will get the picture.

What he said.
12v dc is insanely simple. Read, read, read! just sit there and stare at and try to make sense of that diagram at the beginning of the post and bit by bit it will start to make sense. I am self taught in 12v dc and everything I have learned I learned from the internet. You will learn most by doing.

I wondered why the baseball kept getting bigger and bigger....then it hit me!

So I just want to clarify that you need to replace from the connector back with 12 gauge wire?
