I'm installing a block/pan/battery heater this weekend.
Co-worker used to live in Anchorage and he had the trifecta of oil, coolant hose, and battery heater. This went to a four-way underhood power strip so there was only one wire dangling through the grill.

Report back how you like it; I've read that you get a wierd fog over road surfaces at about -35 that never goes away.
