It is usedLooks like a block heater cord. Did you buy the Jeep new or used?
If I am correct that it is a block heater then yes. Usually leave it plugged in for a couple of hours prior. And when I say extreme cold I mean less than 10* FOk, so if I will be in extreme cold condition I have the possibility to plug in that connector into a power source for heating up the coolant/oil…I have understood correctly?
Anyway I will follow it to see where it is starting…
Thanks!
