Where does this go???

It's a 85 k10 custom deluxe.

Cig lighter or dash speaker?

 

[75gmck25]

Cigarette lighter wiring should be orange, since it provides constant power to the plug.

 

[Memaloose]

What about heater/ac panel lamp?

What about heater/ac panel lamp?

Illumination wires are typically grey IIRC

@75gmck25 is correct, constant hot should be orange

Green wires are typically associated with cruise control and A/C IIRC, I know several GM cars use green for the A/C compressor switch wire

That's a front speaker connector.

Makes sense. Truck doesn't currently have center speaker. Thanks

The truck will either have a speaker in both ends of the dash, or the center speaker. But not both. I don't recall which location used those colors, but I do remember that the lighter shade of green is the ground.

Left and right end speaker plugs have an angled connector though.

I can't tell in your photo if that hardshell connector is straight or bent at an angle.

That is the passenger side dash speaker connector
