Default What is this relay?

Got around to changing out my oil pressure line and found a stray black wire with a melted connector that belongs to something, comes out of what I am pointing to in the pic on the drivers side of the firewall, can someone pls help me out and tell me what this is? 1973 Small Block. Thanks!

My pleasure... Usually this system has been brunt, disconnected creates a huge question mark to everyone left trying to fix it. The relay fit all kinds of cars too.. so they are not really hard to find if you need one.
