Help identify this plug

I'm still learning how to decipher the wiring diagrams in my Haynes manual. In the mean time, can someone help me identify what the plug in the picture is for. Thanks!

If the wires going to it are white with a black trace and light blue then the plug is for the automatic choke (white/black) and idle stop solenoid (lt blue).
Also, it helps if you give more info on the truck. Wiring changes from year to year.

It's a 1976 F150 2WD automatic. One appears to be white/black and the other appears to just be black. They are both similar thickness to the yellow and yellow blue wires coming off the horn relay (16 gauge?). Not the thinner gauge wire like the blue/yellow to the horn relay (18gauge?).

I think if you clean that wire it'll turn out to be light blue. But the White/black trace confirms that plug is the one for automatic choke/idle stop solenoid.

As Mike says, that's the carburetor pigtail - electric choke assist fed from the stator terminal of the alternator, and the idle stop solenoid fed from fused hot-in-RUN.
