Replacing dash harness

[Scott’s 73]

I’m changing out the dashboard on my 1973 Dodge dart four-door custom air-conditioning automatic trans. Looks like I have one extra connector. Just wondered if anybody can tell if I’m missing something. 4 wires 3 pin connector

Sorry no help other than check mymopar.com for factory parts and service manuals.
Looks like a connector to resistor and ac/heater box? Or high beam switch?

In 73 isn't there things like seatbelt warning buzzers, interior dome light timers, ignition Interlock with some other componants

Interlock was 1974 up

Horn relay behind the kick panel maybe?

To me, that looks like the wiring connector for the blower motor switch. And, it is in the right general area.

I was thinking same. Not much on that side too.

I need a new blower switch for sure, I have a connector similar to the 1st pic that looks to be the connector for this switch. I should have took better pictures before I took the harness out. So it looks like a have one extra connector
