This is weird. My GC Diesel did not come with the power cable to plug in the block heater. It has the heater (all of them do). I just called my jeep dealer to get the cable and they say it's not available. Anyone have a part number or any info? This sounds weird. AFIK it's just a regular extension cord.
Thanks,
Billy

Yes, 68186526AB is the correct PN# for the Engine Block Heater Cable for the Grand Cherokee 3.0 Diesel.
There are other posts on this site for 68223420AB and Kats 28500, but that is for a Truck, not a GC. List price for 68186526AB is $74.10 as of 1/8/2018.
From WK2JEEPS.com there are some routing pictures, and they are asking MSRP $67.25
I am being blocked to add a direct path, but go to WK2JEEPS.com and search Engine Block Heater wire routing Grand Cherokee 3.0L CRD and you should find it easily.

I use them for my Cummins, and now for my 3.0. Great site, excellent customer service.
