wiring question

[Deere68]

I have a 76 argosy 26 I have had it a year or so, it has a univolt that was replaced in 2007 and beside it the little fuse panel, has 5 fuses. I am trying to find out what the second fuse, goes to it blows when you put the fuse in, and it has a pink wire. I can see it goes around the wall behind the sink and toilet but not sure from their. Thanks for any input I took a picture I will try to post it later

Call Jackson Center. Often manufactures use the same color code for several years. I assume Argosy and Airstream may have done the same.
