Extra Wires????

[70charger2006]

So I am almost done with the wiring of my 70 Charger and now I am trying to figure out where these wires go and was hoping someone might be able to clue me in. The first pic is of a wire that comes off of the forward light harness and has a connector that would attach to a post (like the temp sensor). The second pic is of two blue wires with black connectors and is part of the Heater/AC Harness. It seems to run along side the passenger side of the carb (I already have an additional blue wire for the AC Compressor in place, these two are extras).

no up on 70 s but think the two blue wires are something to do with the A/C  set up     pressure  timer switch  or something  , its not on a 69  as there are just a green & blue on the engine side of the fire wall  for A/C set up  , as far as i cen remember !  although i could be getting mixed up with something else   
which   harness  is  the two blue wires in !!   that plugs in to the firewall  block  connector !! top , middle  or bottom  

the top picture is the warning light on the brake proportioning valve
are both blue wires 12v feed in he second pic ?
