Does anyone here know anything about block heater models and the cords they use?

My car seems to be mysteriously lacking a block-heater cord. There's a two-prong square plug sticking out of the back of the block, so I'm pretty sure that's where the block heater is. I went down to Canadian tire, but they only have replacement cords with 3-prong rounded plugs. Internet searching has been pretty hopeless (I couldn't even find the 3-prong plug cords), and the technical manual for the car doesn't seem to have anything to say.

Could anyone give me some tips here?

heh heh, I use em on my diesels here in the states but thats about it. I have never even heard of a metro block heater so it must be a canadian option.....however what prompted me to write - make sure from a dealer it is in fact a block heater and not some unplugged knock sensor or something....cause if it is, the results could be electrifying

Heh... good advice. And here I was just going to take an old cord and solder the wires right onto that plug, plug it in, and see if it warms up the engine.

Wierd, since I work at Canadian Tire, and we have 3 prong cords and soem 2 prong ones, all with different configurations.
