Sundance Control Head 6600 854

[oldsundance]

This hot tub worked great until it didn't...  

My first thought was the control head until I removed the side panel to access the wiring and found the rodents had done work. It appears someone has had issues before because there are numerous ribbon cables that have been disconnected or chewed through. The lights have never worked and now I know why. I want to test the control head before I through money at it but I can not figure out where the remaining 2 wires go.

The main wire coming from the main box below is in tact and will still activate the waterfall.

2nd wire goes to aux to possible control the lights.

3rd wiret says iso I believe and goes into the same block.

4th wire does not have a tag

5th wire does not have a tag.

Its a disaster under there and I cant figure out where the remaining 2 need to connect to. 

Any help would be appreciated!

Was that how you found them just hanging there and not connected to anything? Could they be for a spa that has audio installed and just not used.

4 of the 5 ribbon cables were chewed off.  The 5th ribbon cable went into the main box.

there were 4 ribbon cables that I thought connected together but once I got into the next panel the 4 ends were just  two wires doubled over.

Its possible that the remaining wires could run a stereo but this spa does not have that. Ill get a picture and post its a mess.
