Ok so some people have done the all high mod and i personal had had it for a while but i was not happy with the jumper wires. I saw this product by Fleece, and knowing the quality of they products that they produce in addition to this being $20.95 I pulled the trigger on Thursday..

Grand total of $24.80 shipped and arrived last night (Monday)

I figured i would be the Ginny pig for anyone looking for a clean and straight forward upgrade.

This mod will take a <5 minutes. I took 10 minutes total and that was sautering and taking pictures once complete.

This is how the install goes:

Pop the hood
Remove the lid to the fuse box (drivers side at the fender well, this is a black SQUARE BOX)
Now you will want to remove (PULL UP) these indicated 4 relays.

with them removed your box should look like this

If you want to have the ground SIGNAL spade for signal to a Relay for auxiliary lights you will need to sauder this spade tot he board. If yo do not need this then skip this step.

after the board has cooled place it in the fuse box as shown.

With the board installed start to replace the relays (they do not matter the location as they are all the same.

Replace the cover onto the fuse box and shut the hood of the car. Crank her up up and reap your rewards.

I'm running jumpers for this mod but it's a 6 low mod as well as an 8 high (fogs and full time DRL's on low and everything on high) and see this board covers the DRL and fog relay areas. Do you know if they make a board for those mods too?

Any updates on how this board is performing since you installed it a few days ago?

I researched Fleece's website and can only find this single board which turns on the fogs and lows when the high beam is activated. It's a great idea, too bad they don't offer options. I forgot how I did my drl mod- they act normal until the headlights are turned on, then they come on whether I'm in drive or not. And the fogs come on anytime the headlights are on. Then there's my 4 hi mod which is actually now an 8 high. And I deleted the auto headlight function since it caused problems with my HID ballasts. It would sure be nice to have control over all these functions from the DIC.
