What is this wire/plug...

My wiring harness came from a 1989 Suburban. This was unplugged in the Suburban. I started to remove it. I removed some wiring related to an alarm, but this appeared to be factory so I left it in there. It's combined with the head light harness. Anyone know what it is?

Doesn't the relay for the electric fuel pump that mounts on the firewall?

No, the fuel pump relay is on the firewall on the other side and is working fine. I have been wondering what this is for a couple of years now. :lol:

I think that is for a daytime running lamps relay for Canadian models.

Or for the auxiliary cooling fan that they put on heavy duty models.
