Thanks for the post Valiant Indecision.

For comparison sake, we should be asking owners of 2008 FEH from the states where the Block Heaters were installed as a
factory option to check their set-up.
"ENGINE BLOCK HEATER
Standard and only available in AK, MN, ND, SD, MT, WI and WY
states. Other states available via FCSD
NOTE: Fleet Only – Engine block heater optional in all states
with valid FIN code."
Anyone out there ?
Also, here is some more stuff I came across, so I'll share these two borrowed photos from

that show the outer (lower right of 1st picture) & inner (upper left of 2nd picture) connections :
