did you buy those lights from Sewell? (since they prewire it)

Figure out how to get those wires out of the harness? (just need a small toothpick to release it)
I bought my headlights and had to repin to get the LED strips to work since they were not bought from Sewell

I'm assuming you know the colors?

i believe so, green wire is 100 percent and black is ground.

my parking side lights arne't working so im trying to find that fuse now.

Some things to know... If you buy a pre-made kit, you don't have to deal with any of this stuff...

The only thing you have to do is swap the Flasher Relay cube, which sits in the space above the Brake & Gas pedal under the dash.

If you have an IS with AFS, you will indeed get a flashing AFS indicator light.. If you have an IS with just the Halogen headlights, you will not have a flashing AFS indicator.

So far the only known way to stop the blinking AFS light, is to crack open the cluster and block the light that passes through that area with something Black.

Also, the bumper brackets that screw into the bottom of the headlights, will need slight modifications to be attached to the new MY2011 lights.. Basically dremeling some of it off that sits over the LED wire dome cap on the underside of the housings.
But still, only 2 screws will line up after that.

I tried the new step mentioned, of only swapping the GREEN wire location, that DID NOT work on my 2008 IS-F.

So I went with what "thinktwice" originally did..
I snipped the thinner solid red wire, then tapped it into the Black & White wire underneath it..
Then I changed the pin location of the Green Wire to the empty spot... Done.!!

I also tested the Solid Black wire and Solid Green wire to confirm the differences between the 50% & 100% brightness of the LED strip.
I went with 100% power.

Also, the new Flasher relay needed is indeed Lexus / Toyota Part # 81980-06020
That takes all of about 5 minutes to find unplug & replug the new unit.

I only got pics of the Flasher swap so far.. (I was in a rush)

I will try to update this post in the near future with how the wiring looks before and after the slight modification done to the primary male plug connector on the new headlight.

Thanks for all input in this thread..!!
