Brown my friend is for the 4 way valve solenoid, that is if you have a heat pump, ( it uses freon for heating instead of natural gas) perhaps you got the wrong thermostat, if you have a brown you need a thermostat for a heat pump, a regular thermostat is not going to have a brown connection.

I am replacing a White-Rodgers thermostat with a Hunter 44155C and dont know where to connect the wires. I have white, red, green, blue, and yellow wires and none are labeled as to what they are.


The Yellow wire is for cooling, the white is for heating, the red is for power, the green is for blower fan, the blue is your common wire, all you should have to do is color code the wires to the thermostat. The thermostat should have the colors labeled R,W1,G,Y,B or C for common if it's wired correctly at the Air Handler or evaporator. The blue wire should go to B, or C.

I have a cat5e wall plate(tph552) a cat5e wire4 colors don't match and 4 colors do ( brown,orange,blue,green,) are ok then wire has 4 that are white with (brown,orange,green,blue,)stripe. and wall plate...


The wires/colors in a category 5e cable run in pairs. They should be tightly twisted together, mostly white with a blue tracer. mostly blue with a white tracer- mostly white with an orange tracer- mostly orange with a white tracer, mostly white with a green tracer- mostly green with a whte tracer, and mostly white with a brown tracer- mostly brown with a white tracer.The jack you have sounds like a standard telephone or cat. 3 jack. If the jack is being used for a standard telephone line, you'll need to connect one of the wire pairs(usually the white/blue pair) to the green and red terminals on the jack.Make sure that the same pair is also terminated at the main telephone junction.

Suburu radio wire harness. trying to match up with a new soni deck


Hello uze7, Here is the wiring match up for a 2009 Subaru Forester using the Metra 70-7552 wiring harness: NOTE: The actual harness will be listed as a Nissan harness, but has been used by Subaru since 2007. Also, I'm assuming that your Sony deck uses the standard color code. If not, you should have a manual that lists the function along with the colors. Match the wiring by function, not by color (although the colors may be the same). 2009 Subaru Forester Radio Wiring Color Code: Battery BLUE/RED (+) RADIO HARNESS Accessory YELLOW/RED (+) RADIO HARNESS Ground BLACK (-) RADIO HARNESS Illumination VIOLET (+) RADIO HARNESS Dimmer BLACK/WHITE (-) RADIO HARNESS Power Antenna YELLOW/BLACK (+) RADIO HARNESS LF Speaker (+) BROWN LF Speaker (-) BROWN/WHITE RF Speaker (+) BLUE/WHITE RF Speaker (-) BLUE/YELLOW LR Speaker (+) WHITE/BLACK LR Speaker (-) RED/YELLOW RR Speaker (+) GRAY RR Speaker (-) GRAY/RED Metra Harness: Yellow ? 12V Constant Red ? 12V Accessory Black - Ground Orange ?

Wiring on a RCA RJ-45 wall jack


the RJ45 wallplate is not meant for ethernet. It's an 8P8C connector for a phone. Will it work as a network jack? Maybe. I wouldn't use it, but if you really want to try, wire it thusly:

1 Blue --- Orange/White
2 Orange --- Orange
3 Black --- Green/White
4 Red --- Blue
5 Green --- Blue/White
6 Yellow --- Green
7 Brown --- Brown/White
8 White --- Brown

I'd still recommend a CAT5 wallplate with a CAT5 jack.

Blue (C) or sometimes (B) should be your common wire. Look at your schematics and locate common. Your Brown wire is (E) and is emergency heat, white wire (W) is Auxilary Heat, green wire (G) is fan relay, red wire (R) is power, yellow wire (Y) is Cooling and orange wire (O) is reversing valve.

RJ-45 Pins are with the spring tab down and read left to right. Do you have an RJ-45 Crimping tool?
Just use 568-B or 568-A on both ends of the same cable.
