Old Honeywell system only had three wires being used which were red white and blue. We just bought the rth6360 series and not sure if we only need to use the red white and blue as before or if the yellow green brown and orange wires that were in the wall should be used for this unit or not. We have hooked up many different ways and nothing blows.

What color wire is connected to the "Y" terminal on the thermostat.
If the unit you are connecting is a heat pump A/C unit the orange wire is for the heating mode. Normally the "Y" terminal on the thermostat. "R" terminal on the thermostat is the power to the thermostat, "W" terminal is for heating, "Y" is for cooling, and "G" terminal is for fan operation. At the condensing unit for cooling the brown and yellow wires would normally be for the cooling.

glad you posted what colors you do have , cause 2 resources didn't match ,actually 3 , i did find a match to your colors was a 97 year model premium radio, so we have a match .....

black/ light green = ground
dark green = left front spkr +
purple = right front spkr +
blue/white = right rear spkr -
brown/blue = left rear spkr -
brown/yellow = left rear spkr +
blue/orange = right rear spkr +
black/yellow = park lamps
brown/red = left front spkr -
orange = dimmer signal
pink = fused battery +
green/red = radio choke relay
red/white = fused ignition
blue/red = right front spkr -

cheers

djmac62 is also an excellent answer

SOURCE: 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.

The old thermostat has a second stage heat which is W2. The new one doesn't have second stage heat.
The wiring your describing on the old thermostat is telling me you have a heat pump with second stage heat and the new thermostat is for air conditioning only. You will need to get a thermostat for a heat pump.

SOURCE: i have a cat5e wall plate(tph552) a cat5e wire4

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.
