Opening up my dash - found a few mystery connectors

[GrantOv]

Started my winter project of opening my dash to replace/fix electrical items. Many questions - Let's start with some mystery connectors that aren't currently connected to anything.

#1, 2, 3 - these connectors are by the accelerator and under the center lower bezel. Not sure what they were meant to connect to as they weren't connected when I removed things.
#4 - this unused connector is scene through the windshield looking down just above the glovebox area
#5 - this unused connector is hanging down through the glovebox area
#6 - I'm wondering about these blue filters on the inside of the instrument cluster. I was surprised to see them. I was thinking of changing out my cluster lights to LED green but if theses filters are meant to show blue then this plan isn't going to work.
#7 - I broke unfortunately the fuel guage electrical mounting posts in disassembly - any suggestions on where to buy or get it repaired? Does Rocketman do this also? (I need my Tach repaired so I'll be sending this over!)

I forgot to mention a few things - this is in a Mustang Mach1 1972. It had the radio removed so perhaps one of the first few connectors are for the radio?

What are your thoughts? Any ideas?
Thanks in advance!

1, 2, & 3 would likely be 1) clock feed for full console, 2) radio feed, 3) Ac/heater control back light
4 could be the connector for the 3 gages oil, amp, temp
5 likely a buzzer connection (key in ignition, and or headlights on warning ) perhaps seat belt buzzer
6 These blue lenses cause the instrument background lights to give a somewhat blue look glow when the parking/ headlights are on at night. Can be seen better at night than daytime.

Hope this is helpful

Doug is right on with his help on this. Only thing I would correct is on #4. That is showing the main dash harness feed connector (C-702) that connects to harness 13B712. This connector feeds the following four functions:

ckt 14 - Headlamp on - warning relay​

ckt 158 - Key warning switch to buzzer​

ckt 159 - Door Jamb switch to buzzer​

ckt 162 - Emergency Brake light to Emergency Brake switch​

​

As for #5, Doug is right that it is for the Key in Ignition or Headlights on warning buzzer when the door is open. It's not for the seat belt buzzer that's a second buzzer that looks just like it.

Yeah, on #7 definitely talk with Rockman on what your options are.

Good luck with your winter project.

I'll have to look closely when I get back to my car but I don't remember seeing a light on the HVAC control. or maybe mine was replaced some time ago with one without a back light? Enclosed is a picture of a top view. Just the pneumatic connector and main connector on the left side.

Or did you mean the #3 to connect to the infamous Map Light power?

Your selector controls has the opening for the illumination light. Here’s a picture of mine. In my picture you can see that I cut off the connector that goes into your #3 connector. But the pictures show how the bulb mounts into the controller.

I used my missing connector to splice into a new Classic Auto Air system Heater control I’m installing to feed its illumination bulbs. Hope this help.
