    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
