Second block heater?

[Doug Haynes]

Hello all I have a 2022 Ford Explorer ST and love the car but can’t figure out why there is a second 120V plug. I know the block heater in the fron but found another plug on the RH side by the ecm. Thanks

Battery tender? See what is hooked up to because it goes right to where the battery is.

Sure does look like it goes in by the battery. Must be an add on item. Did you buy it used?

Brand new 22 KM on her I’ll do more digging but weird that’s all… plug it in with a meter on the battery and see if it’s a charger…

Battery blanket that keeps the battery warm. It's Canada !!
