Has anyone installed a block heater on a 210G LC?

[Lucciano M.]

I'm installing a block heater on my 210G LC and can't seem to find the correct spot on the 6.8 engine. The instructions say left side of the block, but the only plugs I'm seeing are on the right side. One already has the heater hose on the rear plug, so I'm guessing the front one might be behind the oil cooler?

Just trying to confirm before I start tearing into it any further. If anyone has done this on a 210G LC, I'd appreciate the help.
