Relay Help - Driver Side Engine Compartment

[Jrlew87]

I found this relay disconnected and just sitting on the driver side fender well area. The wires were pulled out if the gray connector also. I can’t seem to find what it’s used for and how the wires go back into the gray connector correctly. I think it may be for the a/c clutch, not positive. Does not have an electric fuel pump either.

I think the real part number is in one of the pictures I found online. My relay seems to be aftermarket/replaced and does not have a part number. Just says 3A20.

Thanks in advance

Did you forget about the other thread you made asking the same question?

It looks like a generic relay, possibly for trailer brakes, but usually its on the other side of the firewall. If everything is working I'd ignore it, probably some custom thing some prior owner added.
