I couldn't mount the bracket to those 2 holes, they just wouldn't line up for me. I just ended up mounting via the 2 holes on the sides. I also ended up wiring it to the cig lighter fuse in the front same with a fuse tap.

I know this is an old thread, but if anyone is interested I am selling my brand new never-installed Wald LED DRL purchased directly from Wald because I sold the car before I got a chance to install them. PM me if you're interested.
