I just got a house and it has a carrier furnace model # 58DR 125-BA and some of the t'stat wires were not hooked up does any one know what termanals for the color wire and there is a 2 wire coming from the unit out side where do I hook them up to?

The wires are hooked up on everything but the furnace

You need to pull the tstat and write down what color wire is tagged to what post of the tstat,, example
Red wire to rh
Yellow wire to Y post
Green wire to G post
White wire to W post
If you have it blue wire to c(common) post

You will need or probably already have a jumper from rh to rc

Then go tofurnace and hook the other end of wires the same way to circuit board if it has one

The 2 wires that went outside tag (1) to the same post that yellow wire went to

And the other to common or where the blue wire fron tstat went to
