2.3L ('83-'97) Mystery Plug near coolant reservoir

[wisepapajohn]

Hello all, I have a mystery plug in my 97 2.3l RWd ranger next to my coolant overflow reservoir. Anybody know what plugs into this?

The other end runs into that big wiring harness at the bottom.

Thanks!

Anybody know what plugs into this?

Somebody knows. But it's not me. It looks like a similar unused plug on my 93, 3.0l on the driver side.

Every picture I can find online it's unused. Looks like the connector on my 91 harness for the MPG "computer" in the Explorer. But mines in the cab... Some something else surely.

Does your windshield washer work?

Thanks all!

Windshield washer does work. Truck runs rough but I'm pretty sure that's an EGR or fuel pressure problem, not a random plug problem.
