Hello. I own a 85 gmc jimmy sierra classic and while I was putting in the new steering column i unplugged the stereo wire from the constant power outlet. Since i did this it does not remember my prefixes.Which wire from the stereo do I need to plug in and where in the fuse box do I need to plug it. Eddie Schmied 1985 k-5 gmc jimmy 4x4. One hell of a coyote chasing son of a bitch.
