Help in identifying this

So I had a peak behind the panel, and found this wonderful fire hazard.  Has been shortening nicely against the GNS480 tray.  Easy enough to insulate properly, I guess the installer must have had a distraction (being kind).  The rest of the wiring looks pretty good.

Now what would require a couple of relays?  Standard KCS55A compass system, GNS480.  PmA7000B audio panel.  KFC150.  Something to do with the annunciator panel?  

Or maybe WoW and Gear Up 'signals' for the GTX345?

Start doing things and see what makes them click or trace out the wires.

I made a complete set of schematics for my avionics install before I started. My avionics guy says nobody does that.

I think, "installer" might be a bit generous.

It's a relay.... or two of them...    One of the might not be working anymore based on the magic smoke it has been making.    https://www.te.com/commerce/DocumentDelivery/DDEController?Action=showdoc&DocId=Specification+Or+Standard108-98007LpdfEnglishENG_SS_108-98007_L.pdf8-1393792-8

what does the "installer" say about them?

Interesting use of prototyping board with no insulation to protect rather lousy soldered connections.This needed to be mounted in a project box for short protection.
