Hi,

I was wondering if anyone knows what piece this is on the right side, which connects to the headlight power supply. I need to replace this piece particular as there was unusual water damage.

 

Are you talking about the gray part?

 

I dont remember exactly which one goes to the headlight and which is attached to the car, but the piece with the lever which locks the two pieces together is sold for $12.86 on Sewell's Lexus Parts.

Part# 9098011893

If you need the part attached to the car, you may have to hit up a junk yard and have cut one off a car for you. It may also have water damage. Hard to say. I tried. Good luck man.
