problem getting DBW cruise to work

[68basket]

I have read through the cruise thread and have the wiring from PSI.

It originally did not have wires in pins 4 5 and 14 at the tac module but psi sent them to me.

I checked pin 6 and it was getting power whenever the brake was not pushed and 0v when pedal was pushed this seemed backwards so i changed the main wire from the psi harness to the white wire at the original brake light switch. I now have 12v when brake is pressed and 0v when not pressed at pin 6 on TAc.

I am just using momentary pushbuttons to get cruise to work. i wired this so that with key on i have 12v at pin 14 on tac, then when i press my coast/activate pushbutton i do get 12v at pin 4 but the cruise will not set.

Unsure what i am doing wrong, i do have standard brake light bulbs.
ANy help would be very appreciated as i am driving this truck to atlanta on friday and cruise would be very nice to have!!
