NO NEW HARNESS NEEDED

I just finished up with this upgrade today and after studying the wiring diagram for the headlights and troubleshooting a bit I found that the simplest method was simply to bypass the hi/low switch and permanently ground the lo red/green wire. Yes, I realize this was already mentioned earlier, but I hope this post can be the end of a lot of the confusion still running through this thread.
I purchased the 9005 headlight sockets on ebay (Pictured Below)

I tested the wires and as mentioned before in Herrorhh's previous post:

Red/Green = lo ground
Red/Yellow = hi ground
Red/Black = LEFT Headlight Power
Red/Blue = RIGHT Headlight Power

I wired in the sockets as follows (pictured below)
(Note: The sockets can come in different colors, mine came in blue and black so I will use that in my examples)

Left Lo = Socket Blue connected to Red/Black
Black -> Red/Green

Left Hi = Blue -> Red/Black
Black -> Red/Yellow

Right Lo = Blue -> Red/Blue
Black -> Red/Green

Right Hi = Blue -> Red/Blue
Black -> Red/Yellow

Also you'll see that I added wire to the hi blue just so that I could extend the reach and distance between the two sockets

Next I gained access to the hi/lo on/off switch socket and I changed the RED/GREEN ground so that it is constantly grounded instead of being controlled by the switch so when the on/off switch is turned to on, the lows will always be on. In the picture I was testing before I cut anything so I have a wire running from the Red/Green terminal to a ground spot under the steering wheel, however I later made a permanent solution by cutting the RED/GREEN wire at the socket and soldered on extra wire and connected it to ground with a screw and ring terminal.

Yes, at this point the Hi Beam indicator doesn't come on with the Hi beams, but at the time of writing this, I haven't felt that it's that big of a deal. However as soon as I do get it working, I'll post the fix. Just ask if you have any questions!

i fond this on Amazon after researching online and re-reading this mod. Thought it could be helpful for a clean setup when doing this mod and adding other lights as well... any thoughts? + some type of Power Distribution Block
