Okay so now I've got it working, sort of...
When I press the Door Unlock, ALL the doors unlock. This is with the setting at factory 1 pulse. No complaint as I'm actually fine with it. But no beep from the truck as in my factory remote.
When I press the Door Lock, All the doors lock. But no beep from the truck as in my factory remote.
The door locks operate as if I operated the switch from the driver door. One press each.
I think the arm/disarm is hosed up. If I fixed that then I'd be content.

I have tested the door lock/unlock lines indicated above and grounding either one produces the expected result. When they are not connected the doors will not lock or unlock via the remote so I had to hook them up.
So my concern right now is I do not have the correct Arm/Disarm signals. I followed the diagram for the 2010 Toyota Tacoma truck as indicated in my first posting. Maybe I still got it wrong and found a second pair of wires with the same colors, it is after all a mess of wires down there. The Arm/Disarm, are they part of the same connector that the door lock/unlock signals pass though because I found a thinner pair of wires going through a smaller connector going to the driver door and that is where I located what I thought was the Arm/Disarm lines.
