IIRC, there's a bolt for a coolant pipe clamp that the kit's bolt replaces.
It's a longer bolt to accommodate the thickness of the heater. The pipe
runs horizontally along the firewall side of the block, under the turbo.
You'll find that the heater conforms to the ribs and bumps in the engine
block and will only fit in the correct spot.

Remember to leave some slack in the cord to accommodate engine movement.
I ran mine up to the gap between the battery and the headlight, where it meets
the other cords for my other 120v devices. From there, I use a low temp rated
cord with multiple outlets for all of the arctic accessories. The molded male end
was then cut of and routed through a hole in the fog light grill. I replaced the
male plug with a hospital grade, clear lexan plug that comes with a green LED,
then secured the cord behind the grill with a piece of rubber hose and a Ty-Wrap:

See text from BEJinFbk for a good description of where the element mounts. The single bolt that holds it on is part of a bracket that mounts directly to the block near the coolant pipe; the bracket has nothing to do with the coolant pipe though. I mounted the plug to the bumper mount by drilling and tapping two small holes for small metric bolts. The plug mount has a swivel so you can rotate it in and out, and a cover, I tried to catch that in the pics. I took the grill out for winter mode for simple access to the plug.
Heater unit. Red rubber piece is where the cord attaches to the heater, the heater unit itself is the square bock part that says "500 W"

Heater unit again, this pic shows the mounting a little better. Cord is routed loosely underneath it. Cord comes with a protective sheath.

All this talk got me thinking...
"Do I want to be without a spare if my block heater dies?"
For 27 bucks, the answer was simple. And it also set me up
with a set of installation instructions to scan. So here they are:
This is a different version of the one that I originally installed
about 10 years ago. That one looked like the image posted above
in Mika's original post. The new one is much flatter and only rated
at 400 watts. It also uses a heat transfer paste that I don't recall
from my original installation, but it should work just fine.

Stay Warm, Folks! :mrgreen:
