Tranny Cooler Filter advice

I know these questions have been asked hundreds of times, but I'm going to ask again. I got the Perma-Cool filter and the B&M 19000 cooler. My mechanic will be installing these on Monday. I wish I could do this myself, as I am crazy about my car, but it's over my head. (I'm more of a computer geek).

I would like to know what I need to tell him to be able to get the most out of this. (i.e. input/output connections, mounting locations, etc.)

Links to install pics would also be greatly appreciated.

Thanks.
