From the vid it looked like 4 presses of the unlock pops the tailgate? Can you change the number or how does that all work?
I am assuming you have those to actuators mounted on the inside of the tailgate like your previous pictures show....did you have to run more wires aside from the auto lock/unlock or can I splice into those? If I can splice into those does that mean I can put all the relays in the tailgate??
Awesome mod again btw.

I do a more detailed write up when I get more free time but it may be a week or so since next weeks a holiday week and have to get some stuff done before family shows up. Let me try and explain what this is doing a little more and the wiring.
Yes I set the TR-7 to count 3 pulses which is really 4 on the tundra cause the first one unlocks the drivers door only then the second unlock opens all doors and tailgate, the decided to skip the 3 cause of safety in case someone else is messing with your remote and hit it that many times it opens the tailgate by accident, thats the reason I choose 4 but you can set it to count 2 if you like totaly up to you. The TR-7 modules are realy handy modules that can be used for lots of things if you wanted.
The complete setup if you include the tailgate lock is 4 wires to the tailgate from the cab. I decided to put the TR-7 module and relay for the auto open in the cab to keep things dry and easier to service if needed.
You basicly tap into 3 wires in the cab, 2 are for the tailgate lock (the smaller gauge wires in the picture) the larger blue one is the one I used for my source of 12V and for a ground source I just used a wire in a frame bold in the door sill there. The other 2 wires are for the auto open motors.
