Is it a spring clip type of heater or does it have a heating element loop?
If it is a spring clip type - they usually don't work very well, but are much easier to install than the other. There should be a spot on the back of the block near the exhaust manifold that you can get to. Just sits in there.
The other type needs to have you remove a freeze plug and install it in place of the plug. I would highly recommend the dealer install that type - very easy to nick something or have it seat improperly leading eventually to a coolant leak.
There are also ones that go in-line with a heater or radiator hose. They heat the coolant that way and helps speed up the warm-up process.
Keep in mind that these heaters are only designed for the "human" factor. Your engine will not generally benefit from a block heater (oil or coolant types) unless the ambient temperature are consistently around the -30 degree (F) mark. They just get heat to spit out faster - that way your butt doesn't freeze to the seat.

But I did find a link that barely shows it (1ZZ-FE engine for a project car):

If you look at the #4 cylinder (furthest one from the pulleys) - above the exhaust header you'll just make out the circular spot on cylinder head. There is supposed to be a freezeplug on the front of the engine as well - but I couldn't see it (might be around the oil filter and under the intake runners).
Hope this helps.
