Red face Help my dog chewed up the thermostat wires

Just moved into my new house last month and my puppy ripped out the small white wire with the red, yellow, blue wires out of the AC unit outside of my house and I went to Home Depot to get a replacement. Not sure where it needs to be attached to.

My husband and his uncle looked at the unit to see where that wire needed to be attached to and couldn't see where to place it. Every other wire was pretty obvious. But this one was M.I.A. So my husband took some pics. Is there anyway anyone can help us with this?

I know it's something small and right in our faces but I we can not figure it out....



This is what we were told to do:
the wires (Low voltage 24v) coming from the house, go to the 2 red wires with the small blue wire nuts that end in their own small compartment. do not hook up to any other ones such as the ones coming out of the round silver cannister (The run capacitor), as they are high voltage 240 volts.


Here is my question.... which red wire do I use to hook the wires to?

Do I have to seperate the different color wires inside the white wire (red, yellow, green, etc)and hook one set to the first red wire and the other set to the second red wire? Or do I just hook them all to any one of the red wires? This may be a dumb question, but I just fasten the wires all together with the wire nuts right? Just want to be sure that I got it right before I ruin something.

Here are a few pics... of the wiring...

the hosted images are very small

So, it's a bit hard to follow via the pix.
I have seen dogs take out the white CABLE before. I'd first recommend you enclose the cable inside a 1/2" PVC flexible conduit, with the appropriate fittings on the end. No more chewed wire.
I'm rather afraid of telling you which wires to connect to, based on the pictures available. But, retake the pix with more resolution, also take a pix of the paper label/wiring diagram that may be located nearby.

Here is a pic of the diagram. The pictures with higher resolution is taking longer to download. Once they are downloaded I will upload here for you to see. We tested the voltage and there's no voltage coming from any of the wires. We checked the circuit breakers.. there's no fuse in the system. Do you know Where would the circuit board be?

that helps

It's very likely only TWO wires from your white cable should be connected to the compressor unit. Yellow (pretty positive about this) and Blue (is there a blue?). Do you see these colors in both the connection box and the white cable? You would also expect to see 24volts AC across this pair of wires if the thermostat is telling the compressor to turn on. There should be evidence of what wires were used. And yes, they should be all seperated.
I don't expect any red wire connection. IF this was wired to the standard color code.

Use the red and yellow that you separate from the green, in the wire you just bought.

Industry standard for the condenser is Red and Yellow.

Pull the disconnect (so the unit will not go on) and turn the thermostat on cool and down all the way. If the contractor pulls in then it is correct.

I STRONGLY encourage you to fence off the condensing unit entirely, as I have seen countless cases of dogs urinating on the condenser fins. This rots the aluminum fins really fast, and kills more a/c's than anything else I have seen. Plus, if you do this, you won't have to encase the thermostat wires.
