Installing CSD fog/spots on 1998 4runner ltd

I read with great interest the article under Products about installing the CSD fog/spots on a 1996 4runner. The install looks super clean. I purchased the CSD's and have a few questions about the installation.
1. What kind of brackets were used to install the lights. I see a hole in the bottom of the bumper, but it would leave the lights protruding too far, not like the flush installation in the photograph.
2. How much of the bumper valance was cut so the lights would fit?
3. What wire was tapped under the dash for the 12 volts to the power switch. I'd like to tap the parking lights but how do I find the right wire?

Thanks in advance for your help.
