Heres what I have - looking down the column from the steering wheel, I have ( 4 ) connection prongs. Two are side by side / two are vertical.
On the side by side, left hand is power feed for backup lights / right hand goes to backup lights.
On the vertical, upper goes to solenoid / lower goes to ignition switch. Hope this works - I haven't got my truck back on the road yet to test in real life !!!
