Thanks for the information and support. I started out trying to find the controller pigtail myself. NO LUCK.
Next tried the local Toyota dealer. They provided wiring diagrams but not much else.
Before trying an aftermarket shop, I went to another local Toyota dealer and explained the problem. The service manager call an associate who knew immediately where the connector was "hidden". The associate cut the electrical tape off the main wire harness behind the kick plate area and there it was. If not for the electrical tape, the connector would have been exactly as shown in the owners manual diagram. The tape hid it very, very well. What a difference talking to an expert !!!
I'm now on track to hook-up the Tundra to my 19 CCD.
