Ok, I have to assume PSI is using a yellow wire for the brake input for the TAC module, so that sounds like it's hooked up correct. The TCC wire placement on the brake switch doesn't matter which wire is on which pin as long as one has power when the ignition is on and the other is hooked to the PCM. So that just leaves the 3 wires from the engine harness that are for the cruise, and the power to the switch. Power to the switch would be hooked to the green wire, set would be hooked to the red wire, resume would go to yellow and on/off would go to the blue wire. This is all 100% depending on how accurate that diagram is though, as I have never hooked any wires directly to the switch, and the pigtail wires being different colors. How are you connecting the wires? They are awfully small to be putting any kind of butt connector on, and also if it's hard wired, it will be impossible to remove the column without having to cut wires. But if that's the way you have it wired up, then check the connections of the wires to make sure they are all good connections.
