    HVAC Wiring
    There are two wire cables.
    One has 4-wires going to the thermostat
    The other has 2-wires

    Looking at the 4-wire cable the white wire has a thick white and black wire. When I replace the 4-wire cable and 2-wire cable do I leave the thick white and black wires connected to the white wire going to thermostat?

    I am going to use a 6-wire cable to replace the two different wires: I assume the light-brown wire in the 6-wire cable connects to the brown wire currently connected to the white wire of the 2-wire cable.

    Can someone please tell me where the 5 wires of the 6-wire cable should be connect at each end I would really appreciate the information. For example where does the Blue wire go?

    I plan NOT to use the white wire of the 6-wire cable. Someone said I hook a wire to the brown wire in the HVAC unit, so I figured it would be better to use a brown wire. So I plan to use the following colors:

    Green
    Red
    Light Brown
    Yellow
    Blue

    I hope this makes sense.

    Best to use standard colors so don’t connect light brown/tan wire. Keep it as a spare. Standard for heating (W) is white.

    The other 2 wire cable would go to the outside a/c unit so that one stays.

    Old:
    G - green
    W - white
    Y - blue
    R - red



    New:
    G - green to thick green
    W - white - stays connected to thick white and black
    Y - yellow - connects to 2 wire cable - red wire
    R - red to thick red
    C - blue - connects to thick brown along with white from 2 wire cable to outside

    First I want to THANK Stuff for his assistance on this matter.

    I have the wires connected as listed in the last message.
    When the system is in HEAT it is blowing COLD air. I placed thermometers at the intake and outtake of the HVAC. The Input 69 F and the Output 51 F. The temperature displayed on the thermostat dropped from 70 to 69.

    Please let me know what I have done wrong.
    I am inserting a picture of the HVAC wiring and the thermostat connections.
    You can see the OLD 2-wire and the NEW 6-wire with 5-wires used.
