If you're talking about the small wires coming off the actual switch inside the lever, then it's Blue- is the 12v ignition, Green- is On/Off, would go to pin #5 on the TAC, Red- is the Set/Coast, would go to pin #4, and Yellow- is Resume/Accel, would go to pin #14. And then you are correct, hook hot with brakes applied to pin #6.

We have set several of these up without using the stalk switch on hotrods. Just a toggle switch on the gray wire (on/off) & momentary push button on the dk blue to engage cruise. Just don't have resume/accel option which we didn't care about.

Or you could just put another momentary switch on the green and have resume and accel too!

Well this is encouraging that I can easily have cruise with DBW.

Now someone needs to figure out how I can manually blip the throttle from the engine bay to impress my buddies when there looking at the engine with the hood up like you can on a cable setup...

Well it looks like I'm out of luck
my PSI harness doesn't have wires in the 5 & 6 pin

Add them. You can get a wire with a terminal out of another PCM harness at a junk yard and add them to the TAC plug, then wire them up.
