Anyone know what this is and where it plugs into?

I’m putting the old girl back together and this wire connector was missed and not marked. Any idea what it is and where it goes? The truck is a 1986 C10. Thank you!

Assuming those wires are Yellow and LT Blue, are the turn signals working?

All I can provide:

The only yellow/lt blue I see under the hood is for the blower resistor. Should also be an orange with/nearby.

Where does the other end go?

I’ll check that. Just put the core support on and haven’t connected the wiring up front yet. Thx!
