Can someone tell me what wires these go to

So I was doing a bit of clean up on the truck and I found these wires/harness just hanging under the dash. It wasn't connected to anything so I pulled it out and I have no idea what they go to. Any help would be appreciated.



This one has 3 orange wires and a orange/blue wire

The bottom one is the resistor pack for your heater motor.

The top pic might be part of the under dash coutesy light wiring harness. However I'm not sure that included a blue/orange wire.

Thanks for the advice...Did some searching in the electrical forum and found this:
http://67-72chevytrucks.com/vboard/s...d.php?t=547368

Looks like it is my heater blower switch wiring harness...

As you can guess the PO gutted the trucks heater set up and left me a pile of mess to fix.

I'm going with either Classic Auto Air or Vintage air to replace everything. Hopefully, it will have all of the wiring harness too

PS.. anyone have a preference between the two (VA vs CAA)

Thanks again
