Alright I did the install. Total time was about 2 hours as I messed with the location for a while but I finally got it. I had to drop the skid plate to access the lines as well. Here are the pics
This is on the drivers side just to the left of the battery. The top line that you see is coming from the tranny and the lower line is the return line that I ran to the cooler.
Here is where I installed the cooler. I had to wedge it in a little bit but it was fairly easy to do. I then drilled some self tapping screws into the cross bracket in front of the cooler and into the extra metal on the Hayden. I then ran the line through the extra hole that is just to the right of where the return line is from the rad.

Here is the bottom of the cooler where I ran the return line from the cooler back into the hard line returning to the tranny. I removed the line that came with the 4runner completely and used the line that came with the hayden. There is just enough line to do this and it would have been crummy if I had to go pick up some more of the trans line because apparently it is not easy to come by. I asked at the Autozone I bought the Hayden at if they had it and they didnt.
This is the view of the return line from the cooler to the tranny.
Hope this helps for anyone that does this in the future! As many have said before: I am in no way an expert and this is simply my pictures of the install I did. I hold no responsibility for what you do to your vehicle if you perform this install.
