Hi everyone. I'm in need of some help on cruise control. I'm honestly at my wits end with this. Any help is appreciated! Here are the important details:

Issue: cruise control box turns on and off, but cruise doesn't work

Hardware:
- 6.0L truck engine, cable throttle body
- Stock cruise box connected to the throttle body with stock hardware
- 4L60e trans
- Dakota HND-2 buttons in cab
- ECU was reflashed by Branden at LT1tech, stock tune with VATS removed

Wiring:
- Stock cruise module
- Pin A: connected to Dakota brown wire (on)
- Pin B: connected to Dakota green wire (set/coast)
- Pin C: connected to Dakota yellow (resume/accelerate)
- Pin D: connected to LS ECU C1 Pin 33
- Pin E: connected to chassis ground
- Pin F: connected to 12V ignition
- Pin G: connected to brake switch (12V when pedal is pressed)
- Pin H: not used
- Pin J: connected to LS ECU C2 Pin 13
- Pin K: connected to LS ECU C2 Pin 50
- Dakota HDN-2 module

Trouble shooting:
- "On" light on HDN-2 does turn on and off with "on/off" button on unit
- Pin A on LS CC module is typically 0V. When "on" button is pressed on HDN-2 module, this pin gets 12V.
- Pin B on LS CC module is typically 0V. When "set/coast" button is pressed on HDN-2 module, this pin gets 12V.
- Pin C on LS CC module is typically 0V. When "resume/accel" button is pressed on HND-2 modle, this pin get 12V.
- Confirmed continuity on all other connections using multimeter.
