Does your truck have gauges for the oil pressure, the water temperature and the charge amps? Or do you have just lights in the dash with no gauges.

The plug with 2 wires next to your oil filter is the Oil Pressure "Switch". it gets power from fuse box (fuse 18). When there is oil pressure (engine is running), the switch closes and lets power through it to power the choke heater (on carburator). The Red/white wire is power. The Grey/yellow wire goes to choke.

I see 3 wires in the diagrams. They show the oil sending unit and switch as one unit, but it must be separate like the picture.
The white/red wire goes to the large round can with the stud sticking out the top. This is the oil pressure sending unit for the gauge.
Then as country bumkin said, there is a switch for the choke. That's the smaller black piece to the right of the sending unit. There is a red/yellow wire that is a power wire that goes to one terminal of the switch, and like country said, there is a grey/yellow that goes up and feeds the electric choke.
