91 Accord Dash wiring

I have a 1991 honda accord and was changing the main fuel pump relay. I went under the dash and saw this plug hanging there. I don't know what it does to or anything that it plugs into. Can anybody help me figure out where this goes?91 Accord Dash wiring Help

The picture is not really clear I can't make out the wires color. Can you describe how many cavities for the connector and how many wires actually the connector has?

You're replacing the Main relay so I assumed the car has starting/ Stalling problem. Is there any other problems? Is the check engine light on? If so, do you know what code(s)?

Edit: Would you like to have the Repair/Service Manuals or ETM (Electrical Troubleshooting Manual) for the car? Give me your E mail address and I'll send it to you.
