89 Forester ticking under dash

[rustfarmer]

Trying to fix my door locks on recent purchase I found that fuse for the locks is missing. When I put fuse in locks work, but I get a slow ticking sound like a turn signal from a metal can up under dash just to left of and above flasher module.  I guess was why the fuse was pulled, to prevent draining battery (it ticks with everything off).  I will pull the part from local boneyard tomorrow, but I also noticed a wire dangling loose in the same area and wonder if anyone can shed light on this part and circuit?
