Help with identifying wires

[Mike80911]

I posted in the 930 forum but figured maybe someone here could help me identify where these wires connect to. Car is a 1989 930 cab.
I removed the fuel gauge to change a relay and saw these 2 small wires inside the dash that were not connected to anything. They have very small connectors on them, I know they are a power and a ground, but I do not know where they should go The power wire becomes live when key is in the on position. Anyone have a clue what they are for? Thanks
