4 part plug, driver's side firewall

[Higher Caliber]

I realize this is probably a long shot but in case there is a rain man in here. I have a 4 prong female plug hanging out of the loom coming down the drivers side of the firewall. I have no idea what plugs into it as there is no plug around in sight that I can find. I will upload a picture tonight after work. Until then, any gurus out there familiar?

Sounds like a similar location as the wiring for my dual tank switch. I think it has wires for left tank sender, right tank sender, gauge, and power to the solenoid.
